Re: 89 C 3500 7.4l TBI with issues
Chevytech helped me with a problem a good while back and after a lot of head scratching and testing I never could find anything wrong.
I finally discovered a lot of my problems were caused by a faulty fuel injector. I was watching the spray from the injectors when I realized that one was spraying a lot more fuel than the other. Replaced them and that fixed my lean condition.
