Question about 1997 GMC Jimmy
I am having some issues it starts to loose power after driving for 15 or 20 min shut it off and restart runs good for another 15 or 20 min replaced o2 censors all but one ofter cat, replaced cat converter, map sensor, plugs wires cap and roater, throttle pos sensor, egr cleaned up and tested good replaced other things too nothing worked. what else can it be throws o2 sensor code every time that is all i know
Sounds like the cpi injector assembly. The fuel pressure regulator may be leaking. Or the poppet valves on the injectors may be sticking or shot. I replaced almost every part on my truck and that is what it ended up being the whole time. It's a common problem on these models. Hope this helped
