Help, I just bought my first DSM

[bruzer321]

I have a 94 Eagle Talon Tsi AWD 5spd, when I bought it, I knew it had a bad alternator and I went through 5 batteries to make the 175mi. trip back home, replaced the alternator, then did a tune-up with platinum plugs and new plug wires, then the starter took a shit so I replaced that and all I have left to do is find what I believe is a vacuum leak. I checked all the vacuum lines off the PCV and boost controller. I sprayed carb cleaner at various spots on the intake still no change. I want to get this car running perfect before I start modding it. It has a RPM sure at all RPMs at idle it is between 620 and 690 and it even does it at highway speeds if I set the cruise. I get HORRIBLE gas mileage and you can smell the exhaust is running rich as hell. The A/F gauge rarely comes off the rich side, it has a blow off valve, an Air/Fuel controller wired into the ECU I dont think it does anything though. A lot of my friends say this is common on most DSM's

Boost leak. www.vfaq.com shows how to make your own leak intake tester.

Also turbo cars don't like platinum plugs. Just use a regular plug.

This is probably a lot of your problem.
