Having problems with your 1993 GMC Sierra K1500 ?
My 1995 GMC z71 when the motor light comes on it starts idleing up and down it. Shifts ruff from reverse to drive and u have to put it to. The floor to get going and solutions?
Does it shift rough due to the idle speed of the engine? If I had to make a guess, it sound like the distributor cap has water in it or has melted a bit. Check into that. Could be a bad spark plug or wire too.
