1989 GMC S15 4 cyl Two Wheel Drive Manual 274000 miles
I have a 1989 gmc s15 with a 2.5 liter engine. My problem is under accelleration it chokes down like the engine is flooding out, while idling it runs prefect. I have replaced the fuel pump, fuel filters, spark plugs and wires, distributor cap and rotor button andprobelm still continues. Do you have any clue what the problem could be?
