Much appreciated - unfortunately my jack just took a dump on me... Broken DSM, broken bike, and a broken jack - it can only get better right..! Thanks guys.

I have a 2G dsm and I snapped part of my spindle. I am trying to put the new one on but can't remove the nut off the ball joint as the stud just spins in situe - any help would be great!! This is really annoying me so much I need a car.

Solved - thanks!

Great information, thanks!

I have a question - what is the cut off between the '1990' and '1991-1993' engine harnesses that go into the ECU? There are 2 pins switched - do the earlier pop-up headlight cars have the '1990' and the 1GB style have the '91-93'? Thanks in advance I really appreciate it - I've got 2 ECU's one...

Thanks, I had the throttle body apart to clean and also swapped over to a non-cruise throttle cable. I have heard the the coolant sensor in the t-stat housing can cause some issues like this? Appreciate the help from a fellow Michigander.

I appreciate the point, but I'm not about to let my build warm up at 4000+ RPM any time soon at all.

When I start my 1g it goes straight up to 3500-4000 RPMs and acts really stupid. Took the ISC apart and manually adjusted to all the way closed - the car still does it regardless. Adjusted the BISS, still the same - also I did a boost leak test and there is a small one at the throttle body but...

Sorry I mean't on not in the accessory position. When I crank I get fuel but then when I stop the starter the fuel pressure dies - this leads me to believe it's a problem with my CAS? Thanks for the information.

Should my fuel pump run when I turn my key to the accessory position? I am having a problem building fuel pressure in my DSM - somebody told me that it should be running in the acc. position - I can only hear it when I crank it and it's a wally so I definitely should be able to hear it when it...

Thanks will do

Hi, what's the best way to clean a head and block to prep them for a new gasket?

Looks like the head studs weren't torqued properly - to me it seems like there was pressure flowing between cylinders and into the coolant passages?Sorry - try the hyperlink to the photos: John Wynne-Irvine's Photos | FacebookJohn Wynne-Irvine's Photos | Facebook

It's a cometic mls gasket - I'll post pictures, but it really looks as good as new. The whole build has only 5000 miles - the turbo more. The head studs were torqued to 70 ft/lbs - I was tired and just wanted get the damn head off, so I didn't check the torque before I took them off, I just took...

Okay, so I removed my head and my headgasket is fine... I was able to just take the studs right out with my fingers though... I know ARP say finger tight when putting them in, but this seemed strange - could this have been causing a 'hg leak' without it being a BHG? - they weren't re-torqued...

Yeah I am really willing to bet it is an HG now seeing as cooling system holds pressure, each piston holds 155 psi, and the block only has 5 k miles on it. Especially after 5150DSM's post which states about the blown coolant line to turbo which happened to me also - thanks for all the...

My 91 DSM has been giving me issues for a while now, they are as follows: 1 - sounds like it is missing slightly at idle as if there was an injector issue. 2 - when running, won't boost at all (it cuts out when you rev it to the point of boost) 3 - when running, heats up very quickly.What...

A while ago my 1g blew the coolant line to the turbo - since then it has been running shitty and playing up. The idle sounds like it is missing slightly, and now, the engine will heat up to 250 degrees within minutes of the eclipse warming up. Also, the coolant looks as if it is boiling. I am...

When I turn my DSM on it overheats very quickly - within under a minute the temp gauge reads 250 degrees - it also cools down very quickly. What i'd like to know is what the differences between symptoms of head-gasket vs water pump faliure. There does not appear to be oil in the coolant. Also...

I got it running tonight.. I changed out all the harnesses as they shorted, turns out I missed plugging the MPI relay in... I have no idea how it managed to run for so long before it decided not to - thanks for your help!

You could have an internal leak in your master cylinder, this is what happened to me. Also, if you have an aftermarket clutch, and even sometimes with OEM clutches, the lines expand when the pedal is depressed causing the slave not to actuate properly. When you bleed your slave, be sure to have...

I have a 1991 TSI AWD. A while ago it got fairly hot (210) and the cooling line to the turbo broke and leaked out coolant. I pulled over and stopped pretty quickly after it happened, and parked it until I replaced the line and put in more coolant. After this, it stopped starting (although it...

The timing is good. There could be so many things causing it.. I have a wideband, however, I also have a crack in my exhaust manifold along a weld which (I assume) would show lean while conditions on the piston would not be lean? You were right about the coolant temp sensor - I replaced it and...

My 1g has been playing up (even more than usual). The other day it overheated (not by super amounts up to 210). Since then, it has been running extremely badly. It takes a lot of cranking to start, and when it does it runs extremely lean while driving and sputters like it isn't getting enough...

I have decided that at the end of the summer I am going to buy a VI-PEC V44 ecu for my 1g. I am just wondering who if anyone is running one of these in their DSM at the moment? Do you have any problems with the system? And how easy is it to wire in and use the auto-tune system (which I have...

I checked my fuel pressure and everything checked out, so I decided to open up my ecu and there was a load of damage from leaking capacitors.. I cross-referenced the number on the ecu and it turns out it had a 90 ecu in a 91. I'm not sure if that makes any difference, but after changing the ecu...

So recently my car began to run really horribly at the SAFC settings that I had tuned into it (660 CC injectors so I was at about -14 on my set up with a hacked MAF). My car started stalling horribly and wasn't running great, when I put my foot down the AFR would be high 12/13's so I turned the...

Hey thanks everyone for the suggestions.. I bought a STRI boost gauge with MAP and installed it with its own source at the T but I guess I got a dud sensor... so back to using the old analogue gauge in the mean time using its own vac source from the throttle body, which now works.. Guess I...

Hey thanks... Yeah I have already ziptied mine up already, and put it through a different higher hole in the firewall too. But what connection do you need to hook up the T to the really small nylon? All the T's i've seen have been huge and NAPA couldn't come up with anything connection wise that...

So I never installed the gauge on my car, and the muppet who had it before me didn't tie it up so eventually depressing the clutch pulled the nylon line out. My question is this: can I hook up the nylon line to the small piece of tubing under the fuel pressure solinoid? As in, push it in to that...

This is the ideal gas law: PV = nRT where P is pressure and T is temperature. Therefore, pressure and temperature are directly related, however, heat causes expansion or pressure, therefore causing the turbo to spin. You can make a turbo spin at 10,000s of RPMS using a high powered compressor...

Thanks, Terry's tutorial was exactly what I needed.. +1 for you!

I know it is metered air that the BOV is letting out, this is why I am wondering whether or not this is what is causing the erratic revving + AFR changes between shifts and at idle every time besides at start up.

Not the same but grab it and sell it they are worth a couple of hundred bucks depending on which harness..Guess it's too late. Hope you saved it!

So I have a 1g which I have spent a while on replacing all the harnesses and going through everything that I ever experienced a problem with, and I recently got it back on the road. When the car is running and driving between shifts it goes really rich, and if I coast in neutral or let it cool...

Thanks.. I will look into that. My first problem is cutting and welding onto my cold air intake as that was put together by my buddy who tig welded it all.. It might be easier just to get a new cold air intake I guess as I don't have the equipment. Do any of you know where i could find a cold...

I have a greddy type S bov on my 91 talon, and am wondering where, if anywhere, I can buy a re-circulation kit? Or if you can use the stock 1g recirc stuff to apply on the type S? I have no idea about this, and it's causing idle issues and all sorts of annoying stuff. Please help - thanks. And...

Thanks I wired it into the AC switch and luckily that still works, while having the other into the wiring passenger side. All resolved, thanks again.

I solved it by getting a new relay wired in and bypassing all the stock wiring as I couldn't find anything that was obviously wrong with it, and it still wouldn't work. Now she's running like a champ - thanks for your help.

Okay well I was just figuring on hot days and when I know I am going to be gaining a lot of heat I would prefer to have it so I could control the 2nd fan via the AC switch. When I bought the car it didn't have the stock fans, the guy somehow squeezed a 14" or whatever, and that flowed terribly...

That's as simple as I hoped it'd be.. Thanks. So I assume when you wire them in like that they behave as the stock fans would? Also, as they are high CFM fans if I wanted to wire one in to the AC fan position, and simply wired in the ground and live, would it behave like the AC fan (turn on when...

I got myself a mishimoto rad + fan combo, as far as the wiring goes how can I wire it into my 1g harness so it gets triggered by the ECU and on the driver side the AC fan switch in the car.. The fans just come with a ground and +, but the original fan wiring has four wires, a black, blue and...

So with the wide band you want it (or I do) to idle at around 14.5 -- 16.0 on the wide band and around there also for highway cruzing. The karmen setting simply monitors the amount of air your engine is taking in through the MAF sensor. In order to set it you have to first set your throttle...

91 TSI AWD on a 2.3 stroker & 60trim.. St Joseph, MI

So I have hardwired the starter and everything turns over fine. I am assuming that it is down to the connections where the aftermarket alarm was present (I already took it out while doing the rewire, as the short traced back to it), I guess I must have missed something. It appears it was only...

Thanks i'll give the tests a go. It is a 91 MT trans harness so everything it the same, I also replaced the harness that goes across the dash. I replaced the starter already and the plugs are good, so the starter is definitely good. As for the ECU, I've got 2 so I already changed them around to...

I have a 1g DSM that needed to have all of the wiring harnesses replaced due to a bad short. The short led to the aftermarket alarm which had an immobilized built in. Before I changed all of the harnesses around, the car started fine although eh starter was starting to give out. When the...

The starter actually clicks, sorry, I couldn't hear it before, but it just does not start the engine... Any ideas as far as that is concerned? Clearly there is continuity to the starter through the harness, but no power getting to it?

Okay so by fried I mean one wire shorted and burned all the sheath and melted the sheath around to many other wires..This short extended from my fuse box in the passenger side engine bay through the lighting harness across the connection to the interior harness, through to the connection into...
