Sometimes i will start the truck and the check engine light comes on. When this happens, the throttle doesn't work at all. I have had instances where the light was off and the throttle didn't work either. I noticed yesterday if i pick up the back of the pedal a little, the check engine light comes on and the throttle quits working. i let it back down and after a few seconds the light goes off and the throttle starts working again.
i don't want to start a seperate thread so here is the other problem.
every morning when i start the truck, it puffs white smoke and chuggs a little rough. it will puff for a few minutes if you let it idle but if you get on the road and floor it, it billows white and black smoke for a few seconds and then all is well. no smoke and it runs great.
