I'm Awesome
My buddy has a 1993 Chevy 1500 2wd 5 speed with the 4.3 with 250,000 miles. We tried numerous things to fix this problem. New maf sensor, fuel filter, fuel pump, re timing, tune up, catylic converter. And nothing seems to help. When the truck is cold it wont take off it will spit and spudder all the way somtimes so bad you cant make it up hills or even idle. It will start no problem but the idle will pick up and go down so low it almost stalls. Once its warm it seems to go away, until you start it again even when its warm it does after you shut it down and restart. He's had numerous mechanics put it on their computers and they pull nothing, the check engine light isnt on. Two mechanics have said the cam is going bad. But wouldn't the cam do it all the time? What is the problem with this truck?
Thanks.
