Question about 1999 GMC Jimmy
I have a 99 Jimmy that idles very roughly when starting out and won't accelerate until the engine has had about 30 seconds of running. Even then the engine still stutters when climbing hills and absolutely no acceleration when trying to pass someone. I have replace spark plugs, wires, and fuel filter. Any suggestions as to what to try next??
Maybe have your exhaust checked for plugged catalytic converter

Have you the intake off? if so check for trash in the fuel ejectors. I had the same problem, I just replace the fuel meter body with one from the junk yard
