i just did a tune up on my tbi 5.7 and a few mods(throttle body spacer headers and aluminum valve covers)and i cant get her to idle for more than 30 sec. with or without the advance plugged in(i took the intake off and cleaned it timing is off) if i play with the throttle it will stay running. i dont think there is a vacume leak i sprayed everything down with wd-40 and there was no change. if anyone has any ideas feel free to shoot them my way......

 

Do you have a timing light to make sure it is timed right?

 

i have a timing light i know the timing is off but i cant get it to idle long enough to set the timing exactly,before i changed the plugs wires cap and rotor it idled fine but the plugs were so fouled it idled too rough to set the timing.....

 

NEW UPDATE....wont stay running at all run for 30 sec then die start right back up then die check engine light is on now....could the fuel pump be bad these motors are low fuel pressure systems arent they?......anybody wanna buy a 95 reg cab long bed

 

Haha how much??

 

im hoping thinking simple is gunna help me on this one imma pick up a new fuel filter tmrw but hey everythings for sale for the right price ruffneck gimmie a price i cant refuse(im all the way up here in pa btw)

 

Jus tryin to throw a little sense of humor. Would really help if you could get that code read to what its throwin. I know you cant get the truck up there but, hmmm Im gonna think it would be ignition since it happened right after you changed the cap and rotor.

 

yea i figured you were jus kiddin....does anyone now how to get the check engine light to blink so i can count the engine code??

 

Parts store sells a metal clip now for a couple bucks to do this.

 

Paper clip or a piece of wire. Jump the plug and hte engine light will flash. I just do not recall which hole to stick it is.... Okay I hear the wise cracks coming... Bring em on... lol
