1999 GMC Jimmy 6 cyl Four Wheel Drive Automatic 157000 miles
I have a vortec 4.3L and when I accelerate the RPM go up but the speed wont increase very fast. Also when I get going the engine will struggle and pulsate. I checked the fuel filter and air intake. The Mass flow air is new. Can you help me please?
