Описание: Second video. In this one I put the air filter cover on and rev the engine a couple times. I've owned this truck since last spring. Shortly after buying it I had to put a new fuel pump in the gas tank. It quit working and wouldn't pump at all when the key was turned to the run position. I then put new plugs, wires, cap and rotor. I've also tested the O2, water temp, throttle position, manifold pressure and air temp sensors and all were good except throttle position which I replaced with new. The trucks trouble code system doesn't work. When I use a GM code reader and turn the key to run the engine light only flashes once then stays on permanent. One time I was able to get it to work by unhooking the battery and removing the computer and prom chip. Then reinstalling. The engine light would come and then I was able to get the codes to read a couple times then it went back to not flashing the codes. I'm thinking maybe the computer or chip, or both might be bad. I've checked all the vac hoses and while some are weathered, none seem to leak causing the uneven and high idle.
Повторяем попытку...
