Video of what my car is doing.

1993 GSX Eclipse cutting out in boost - YouTube

Not sure what is going on. It's idling high like there is a vacuum leak, but I couldn't find one. One of my lifters has a slight tick, could this be a knock sensor issue?

 

[bcracecar]

I doubt it's the ISC, I've seen them go out and it's a very different behavior at idle and it doesn't affect much of anything once the throttle plate is open. Vacuum (boost) leaks have to be HUGE to actually make the car shut off. I had a capped 5/16" port on my intake manifold open up and I could still limp the car home with a little throttle control. Common sized boost leaks though, can absolutely cause headache inducing runability problems like you're having.
EDIT: Had to reread, saw you've done a boost leak test already.. At this point a data logger would be extremely helpful, I'm almost starting to suspect a TPS or MAF issue.

I think I may just take it to a shop and see what the hell is going on.... This car became more of a project than I thought it would be

I can sympathize. Come talk about it in 20 years. Datalogger is cheap. Good tool to have.

Well theres high idle and idle surge when warm I assume?

Let me check your profile, here quick and come back.

Please update your profile..

There is nothing listed at all..You also may have no mods..I just thought I would say something.

There is nothing listed in the mods section because there is none. Car is completely stock.

Best place to buy one?

 

[Bud92gsx]

Ahh yes..Well then, now that we have got that out on the way.

Ok..Well.Let me find some links then.

Hey look who's linking this stuff http://www.dsmtuners.com/forums/fre...ons/172175-idle-surge-problems-solutions.html

We have this to read up on DSM 4G63 Maintenance Guide - DSMtuners

We have alot of stuff you should know here

 

[pauleyman]

I don't know what's out there anymore but I've used digital tuning for as long as I can remember. Palm pilots on ebay for 10-15$.

 

[Bud92gsx]

Well I've just been informed we have more than one issue with your car.

The cutting out, the huge exhaust leak going on, the idle surge..So where do we start?

That "exhaust leak" is the previous owner brilliant idea of how to make his car sound great... Cut it. I ordered a new cat back yesterday. Waiting for it to get here. Until then, the cut out issue is probably the biggest issue running wise and I'm hoping that it may be linked to the surge issue? Probably not with my luck though. I work full time and go to college in the evenings, so this car is taking up every last bit of free time I have. I just want it to work

 

[Bud92gsx]

I'm just saying..I can go out right now..Pull my DP off, or my "cat" and take a video..

It's gonna sound all loud, the turbine spinning will be more audible.Just like in the video.I'm not gonna sit there and and go that high in the rpms tho for that long.

You may also want to get rid of the stock DP as well..I dont have the pictures on my phone, but the stock 1g flex mesh crap, is waay more restrictive than I thought it would be..I was curious, and found out.

Someone just posted a complete pocket logger setup in the classified section You can also test the operation of the TPS with a multimeter.

I'll take a look! Thanks! And as far as the multimeter testing goes... How is that done? I've never done it before or seen it done.

I'll eventually get full exhaust and manifold. I just simply don't' have the cash right now and am more concerned about it working properly than going fast.



and i just wanted to say thank you to everyone who is helping out this DSM newbie since I've joined this forum. I've never really worked on anything other than pushrod v8s and dodge neons . I'm not too bad with a 420a though! i appreciate all the input guys.

Also, I see that PDA needs the data logger software loaded onto it. What is the cost on that and where would I need to get it from?

 

[muddfisher85]

What are your spark plugs gapped to? Pull the wires out of the coil and check on the shape of the wires and coil. What plugs are you running?

 

[Bud92gsx]

Is the 1g droid logger thing still goin on?

Replaced plugs and wires. Gapped to factory specs. (car is stock) problem still occurs. running NGKs.

I have a stupid iPhone that can't do anything so that won't do me any good... What was I thinking when I switched from Android?

 

[pauleyman]

Gapped to factory specs

Which is? and what plugs?

 

[bcracecar]

I want to say .032? I know I had them print me off a sheet that had the gapping spec on it. They are NGK GP platinums

Well we mise well start with your plugs..Get rid of the platinums..Ngk 6es, gapped at .028 not .032..

To be honest I don't remember exactly what the gapping was... I just know I gapped them to what autozone's data base said they should be. Are the plugs I have no bueno?

 

[Bud92gsx]

Correct..Platinums you cannot also gap..There pregapped, and if you try to gap them, most commonly the platnum comes off.

Here are what is reccomended. STM: NGK SPARK PLUGS | BPR9ES | BPR8ES | BR8ES | BPR7ES | BPR6ES | EVO VIII | 90-99 DSM

I did not change the gapping. Just checked it before I installed. I have a feeling that this isn't a plug related issue though...

I'll check out the link. Thanks for your help! Do the coils on these cars usually go bad?

 

[Bud92gsx]

They can and are known to in some cases..But back to the plugs..Thats what You will want,like asap before we go any further..

You cannot go forward if there is something stupid and simple that needs the right part.

Roger that. Ordering them now! Now what?

 

[Bud92gsx]

When you get them...Gap at .028.

 

[bcracecar]

One of my buddies had a set of plugs he never installed into his because he totaled the car. I installed the 6es plugs and gapped at .028, still runs like shit as i thought it would...
