well i checked into the valcover gastkets and the drivers side was replaced with the new harness but not the passenger. I also removed my fuel filter, its been on there for about 1000 miles and clean as can be, no black or anything so that must have been coming from the infectors they replaced or some bad fuel, I orded a gaskent and harness kit that should be in thursday. will try that thursday night and go from there. Also it lopes really bad when i start it after its warmed up at idle for up to a min at times, read somewhere to start in nuetral and it wont do that but it still does it in neutral.......?

I've had electric fuel so long I don't remember where its at or how to clean it. There is a screen that you use a Q tip on that can get clogged.

is it down in the filter housing or something? ive herd others talk about it to but im not sure where exactly. I dont think its a fuel suppy issue tho, doesnt act like its staving for fuel it just acts almost as if the timming is off or something electicals like that. It always runs best when its cold and the warmer it gets the worse it will run. I will check into that scree tho, heck anythiing is worth a shot to try as long as it now back in the shop getting "fixed" when all i get is a $1500 bill and a pickup that runs exactly the same.....

For the FPR, you will need to take the fuel filter out, and you will see a hole about 2-3 inches down from the top of the fuel bowl, on the drivers side. The screen is in that hole. I use a zip tie with a square cut end to gently scrape the screen. Most use a q-tip with the cotten removed.
