Re: need help, truck runs like crap please help
I am not sure what to say. Personally I would consider checking to see if the Fuel Filter is clogged or not. Perhaps remove it (if it has one) and blow through it the direction the gas goes through. If it seems clogged replace it. [img]images/graemlins/wall.gif[/img]
And I agree with snowmancat about the carb cleaner around the intake manifold. Don't let it get sucked into the card @ idle - just spray it around the entire intake manifold where the bolts are and the intake seats against the heads. Also, if you don't find any change in idle when doing this, still take a socket and socket wrench and make sure ALL of the intake mainfold and carb bolts/nuts are tight. Even a slight 1/4 turn on a loose bolt can make a difference.
If you don't have a Chiltons I suggest picking one up. Also, most of the things you have mentioned involve electrical. Perhaps maybe it's a fuel delivery problem - though you did say you replaced the fuel pump. The other thought is what year did that Q-Jet come off of? Just some food for thought.
Good luck and let us know! [img]images/graemlins/thumbsup.gif[/img]
