Hi:

I have a 94 Z28 which stalls while driving. The first time it happened I called a tow truck. While waiting for a tow and about 15 minutes I tried starting and the car started. I drove home ok. I took it to a shop where they scanned it for codes but came up clean. I took the car home and a day or so later I experienced the same problem.

Can you help??

 

Put a fuel pressure gauge on it and check pressure with the key ON and also while the car is running.Key on it should be 41-47 psi

 

iac motor?
