[s-cars] ARGH!! Stalling at idle

[RM]

Mark, no matter what anyone says, fuel pressure is not the issue here. FP is 
vacuum adjusted, not temp. driven. Yes, in effect the FP reg. could be bad, 
but it would affect more than just cold starts. The CTS is the leading input 
to the ECM for cold starts. Check here first. Having said all this, your 
95.5 is possibly OBD-2 compliant and requires proper experience, info 
systems and tools to diagnose correctly. Most anyone can visually look for 
problems (broken vacuum lines or hoses) and most everyone can replace 
sensors and switches out of frustration. I have at my disposal the real 
factory info system and thousands of $$$ of quality diagnostic tools, and i 
still can find difficulty finding problems, esp. with older cars that have a 
few miles on them. Unless this is a common problem with these cars, which it 
isn't all that common, you'll be subject to allot of specualtion and that 
could cost you more than if you took it to a trusted technician.
