I have a '92 Z that stalls whenever you sit at a light or idle through a parking lot. It is worse in warm weather. I have checked the codes and it said EGR was the culprit. Has been replaced twice. ECM has been replaced. Still have the same problem. Any recommendations? Wolf

i had a beretta that did that, turned out it had a cracked head that someone JB WELDED! so then the crack turned into a hole but it never did anything but die at stops.

Yeah, my ex's Z34 did that too, always at the stop lights....
First, replace the fuel injectors, cuz probably they need done anyways, next be sure to always run synthetic oil in those cars... i'm not gonna get into reasons unless you ask.
The Chevy V6 family likes to eat up injectors.... especially the 3.4L TDC.
If the injector aren't the problem, check EVERY spark plug and wire in the car, then check the coil packs.... i've heard both fuel and ignition problems occuring in those cars, but usually injectors....lol

I'm having the same problem did you ever correct it?
