first off, thanks to anyone who bothered to click this link
secondly, we recently acquired a low-mileage '91 Z28 with a bit of a problem. It fires right up, to about 2000rpm, then drops down like its going to idle at around 1000rpm, only problem is that it KEEPS going down until its limping along about 400-500rpm then sputters and dies, try and give it any gas and it immediately stalls, no change in rpm whatsoever. Fuel pressure problem, right? We replaced the fuel pump and fuel filter and it STILL DOES IT, even with almost 50psi fuel pressure
maybe TPS OR IAC could cause this? only thing left fuel-related I can think of is the regulator. I'm no master mechanic, so I'm stumped...anyone have any ideas? thank you anyone
