I installed a new fuel filter and check valve (the check valve was toast). No improvement on the start of this car. It still wants to stall when first started, but if I keep my foot on the pedal so the rpm is like 1000, after about 30 seconds the rpm will rise on its own to about 1200-1250, then the car runs fine. After a normal idle, though, if I throttle the rpm to maybe 1500, then let off, the car wants to die. The idle goes so low, without recovery to normal, that it just runs down and quits. However, normal driving it runs fine. If you punch the pedal the car wants to fly:):)...
Just not sure where to look. I started this post as the previous was getting a little lengthy. I have checked for vacuum leaks, removed and disassembled the IAC (it was clean, and bench tested just fine), replaced the main intake hose from AMM to turbo, checked throttle linkage, removed and cleaned the throttle body.
Thanks for any suggestions--Tyler
