New to the DSM Game, already got troubles

[triggerx]

First off I want to say whatsup everyone, pretty nice forums after I have searched around a bit.
Lol Im sorry my first post is a question or a plead for help unfortunately.
Alothough Im loving this DSM Car, A 1990 Eagle Talon Tsi AWD, its been throwing some problems with me.

The AfterMarket Gauge is reading extremely rich, unfortunately its all the way on the rich side as far as it will go(however Im starting to think it may be inaccurate). However I did fail emmissions, so its possible its not a total lie.

The readings were as followed

You must be logged in to view this image or video.

Now my Goal Right now is to pass emissions, so then I can tune it up and Start Modding it out!
However after
-Replacing the old Platinum sparks with NGK Copper ones
-Replaced Spark Wires
-New Valve Gasket(as well as a copper sealant)
-Took out the KnN air filter and put in a more restrictive one

The aftermarket A/F gauge still reads the same..

Unfortunately there is still much I need to learn about this car, because we got it at an auction and it has already been modded out with things such as Aftermarket A/F Gauges, Turbo Pressure Gauge, New Rims, Exhaust(High Flo Cat is welded on), After Market AlarmSystem(Not likin that), KnN air Filter, etc.
I say etc because I honestly dont know how much this car has actually been modded out.

So yeah I have no clue what to do now. I see a hairline crack(really small) on the exhaust manifold but i dont think its enough to make it that rich.
White Smoke Did come out the exhaust earlier today, no clue why, maybe a bad head gasket or somethin.

Lol thats why I have come to the great minds here on this forum.
Any suggestions?

O if you guys need any pictures let me know.

Thanks alot. To answer your questions.
I do have stock injectors(blue tops), and the MAF isnt hacked.

NEWER GALLERY
Another Gallery, alot shorter, better view of Fuel injectors, etc.
ImageShack Gallery

Would this really be much of a problem though? I mean if fuel delivery system is stock, and the only thing thats really changed in the engine is the Aftermarket fpr, and intercooler, is there really a need for a hacked maf? The car is probably pushing a little over 210 horsepower so shouldnt alot of the stock parts be able to take it.

Yea, they are stock injectors blue tops. I'm pretty sure since it has a fpr, I would bet it has a wally 255 lph aftermarket fuel pump. The hacked maf allows you to run a few more psi before hitting fuel cut. The front mount intercooler cools the intake charge from the turbo and it allows for a denser air charge. The front mount would allow more psi aswell. Fuel pressure should be about 37 psi as the other poster said.

 

[Rex2342]

If the maf isn't hacked just leave it alone for now. No sense in causing more issues before we solve the first one. Do you know if the previous owner put in a 255lph fuel pump? Also what boost is it running and have you boost leak tested yet? I'd fix that throttle cable too. You really need to get a logger to see what it's doing. That A/F gauge isn't accurate at all for reading rich/lean conditions and we may be chasing a problem that doesn't exist. I think you are relating your failing of emissions for the rich reading on that gauge and that's probably not the case. The simple fact that it's an older car with 140,$#% miles could be the only factor as to why it's failing emissions. Does it still have a catalytic converter?


Edit: Get a cover on that timing belt too!

 

[Spoolin18]

Like poster said above, its hard to chase down the problem without doing a few things first. With that being said, check for any vacuum leaks? most especially to the AFPR's nipple? One of my old hoses to my FPR developed a small tear and left me running richer until it was replaced.

 

[Spoolin18]

Does it puff any black smoke?

 

[Spoolin18]

A leak after the turbo will make you lean under vacuum and rich under boost. A leak after the mas but before the turbo will make you lean all the time. To be rich at idle you may have a fuel pressure regulator overrun from a larger pump other words the afpr could be bad, I had a aeromotive go bad on me once and it was overrun by the larger pump, a bad 02 sensor could also cause it to be rich. A datalogger would be useful.

Black Smoke, no not at all actually.
However I have seen white smoke occasionally when the car had accelerated in front of the driveway, under reverse as well as the 1,2 driving gears from what I saw.
That may be a seperate problem though, or related, because cant a boost leak lead to white smoke?
Although if there is one, its not a major one, I hear no hissing or shhhhhh noises whatsoever.

As for the boost, its hard to tell, I havent seen more than 7-8 pounds of boost when the car had been driven before.

So it definitely could be a turbo leak, we have put the car under some hard acceleration, like a 0-60, but it doesnt seem like its building much boost.

I still have to check for vacuum leaks as well as boost leaks, and honestly I wouldnt be surprosed if there were some. So many of the rubber couplings seem like they have been tearing, as well as there is tube that seems crushed in.

And as for the A/F Gauge, I've been suspicious if its been accuarate or not, simply because its reading rich all the to the right and doesnt change from what Ive seen.

So I guess my list should be as followed
-Find out if gauge is accurate
-Find out if its a stock fuel pump or not
-Check for leaks
-Fix that throttle cable

O yeah, it has a catco catalytic converter on it, and its welded on from the looks of it.
Im assuming its a high flow cat

Edit: I wished I lived somewhere alot cooler than AZ, Its just so hot!

Also where is the fuel pump on this car?I think I see it, but Im not completely sure.

 

[Rex2342]

The fuel pump is in the rear hatch area under the cover held in by 2 screws. The A/F gauge isn't going to be accurate enough to tell you anything even if it is working properly. That type only reads accurate at WOT and even then it's not good to tune with.

 

[EFDfire446]

try changing your o2 sensor that may fix your running rich problem and as for the emissions id guess the cat. converter. And like the others that have replied fix that throttle cable i know your missing a bracket u can check a salvage yard for that part, the bracket goes where those tie straps are. good luck and god bless.

If a pictures a thousand words than a video is gotta be better. Sorry about the audio tho, the mic is a lil weird on the camera.
YouTube - Talon Running Rich

But im trying to make it as easy for you all as possible.

And thanks so much so far you all have been really helpful. Ive been busy to day so I havent had a chance to really test for leaks.

However I plan to go the junkyard tommorow.
So far my list consist of
-Turbo heat shield
-Timing Belt cover
-Some Bolts
-Bracket for the throttle cable
-New Manifold from a 2g for future modding
-Maybe even a newer MAF (although these two things wont be added later, till the car has been tuned and driveable)
-Maybe an EVO III O2 housing if they are interchangeable(that'll go on later as well)
-Try pullin a few 02 sensors
-

Anything else I should keep an eye out for?

I just noticed its narrowband a/f gauge. Those are not real accurate, and like someone said not good to tune withat all. Are you sure its white smoke? It looks like a 2g exhaust mani on it, but you said it has a crack so..
the evo3 02 housing is not a bolt on product, it fits the turbine exhaust housing but don't bolt up to the exhaust downpipe or even an aftermarket one for that matter. You have to fabricate it a little. You don't have a P.S belt on your P.S pump. Why, I don't know... It might be your cat causing emission failure, IDK. My state don't do emission checks...atleast not yet. Make sure all your connections in your hoses are good, and your intercooler connections is good, check the 02 senser. How is the idle on it? Does it miss?

 

[rush2252]

Correct me If Im wrong but I believe your car was formerly owned by a member on tuners.. Its looks very familiar? Ask around maybe you can get some answers to your questions.


EDIT** that timing belt is PAST due for a change its saturated in oil.

 

[InfiniteGSX]

I have not seen anyone ask this guy what kinda A/F Gauge he has. Unless its a wide band, its just ####ing up the car by damaging the O2 Sensor signal to the ECU. If its not a wideband o2 sensor, its not actuate at all. In fact you can toss it in the trash because it isn't worth a dime, unless you know someone that wants the LED's inside of it.

I would be checking your ecu wires for defects. When I got my car it was running extremely rich. The O2 sensor wire wasn't even connected, they had a pos A/F gauge installed. So I had to solder that connection back together and the car started running great again.

You should get a set of NGK BPR6 or BPR7 Spark Plugs, because thats what the car requires. Puting a more restrictive filter in wont change a thing. Put the K&N Back In. Listen to everyone involving the fuel pressure. Aftermarket fuel pump or not, your system needs to be running on the proper fuel pressure. I honestly would check all the wires going to your ECU for faults, and repair them if there are any. You should be changing O2 Sensor if its defective. Or hell, make sure its even connected. Check for vac/boost leaks.

Don't even bother with the 2g manifold. It does not match up to a 1g head trust me on that i tried. It will bolt up but u will have alot of boost leaks on the manifold because the ports on a 1g head are larger than that of the 2g manifold and head. Oh and when you start putting parts back on like a power steering pump belt or the throttle cable bracket just ask I'm sure alot of us have played with all those parts. Good luck.

I tried lining up both manifolds too and it didnt work

[skatershawn]

I didn't have a problem putting the 2g mani on!!!

 

[skatershawn]

Oh but that isn't why i came to post here sorry!

I have been looking over your pictures for a few days now and researching and not sure how this effects anything but on you throttle body you have the ISC sensor and on top of it there is a male plug that there is nothing plugged into... that is part of the ISC..... and the other female plug next to the battery you showed on the video looks like the MAF sensor plug... that NEEDS to be plugged into the MAF... either the stock 1g.... the 2g... or a translator for a GM MAF!!!

I hope this helps you out and i hope you get it back to proper operations!!!

good luck!

 

[skatershawn]

ok i looked more into the video and i believe i may be wrong about the MAF but im completely sure about the ISC.... but once again im not sure what problems that would cause but not being plugged in!!
