Engine Mechanical problem
1992 GMC Jimmy 6 cyl Four Wheel Drive Automatic
Dear Sirs,
I have got a GMC blazer when i start it gives black smoke and the engine vibrates but as i put in drive position it goes off. I had showed it to various mechanics and they said the TPS is not working. Then i changed the TPS still the same problem occured. Could you tell me how much volt comes in the 3 wires of the TPS wire terminal. thanks
