I have a 1991 Chevy S10 Blazer that is stalling and idling very rough when pressing the gas pedal.It acts like its not getting any gas. The problem seems to be even worse when the weather is very hot (Arizona Summer heat).
I have already replaced a number of parts and still having the same problem. I am hoping someone will think of something I haven't.
I have replaced the fuel pump, fuel filters, TPS, Map Sensor, cap and rotar, and a part that mounts to the side of the throttle body (not sure the name), the ignition module and ignition switch, air filter.
Any ideas????
