Iam really stumped. I have a 89 iroc 350 tpi. I have to start it with starting fluid. it runs OK ( kinda on the rich side) and idle it speeds up and down (sounds like a mild cam lol) Ive replaced everything in the fuel system except the injectors. My resistance readings from front pass side are (16.0, 16.2, 16.3, 16.3) and from front driver side are (15.4, 15.9, 16.3, 16.4) these are oem as far as i'am aware of. ECM has been replaced , and has good fuel pump press to the line. Any idea's or a since of direction would be much appreciated. thanks! Towinainteazy

 

I have the 89 GTA Trans Am and it starts fine initially but runs terribly. If you shut it off right away it wont restart but does with starting fluid. Fuel pressure is good, ignition module is new, new mass air flow didnt change a thing and it has a new fuel pressure regulator on it. If the car sits for 15 minutes after being shut off will restart also without fluid. It has new wires and plugs. I was told that 6 of 8 injectors have high resistance. Should I change them or could it be the computer? I'm highly frustrated too.

 

I think you might have a bad injector when they heat up.
