yeserday i was trying to see where i wanted my idle set so i was putting a piece of strong cardboard over the throttle bodie to slow the rpms. did not do much but make it stumble. i took the cardboard off and it returned to idle. so this morning i started it and it idled like it had a huge cam, i think it may have only been hitting on four cyclinders. it ran for about 10 seconds like that and died. now it won't start at all but if you floor it, it will stumble a little but won't start. fuel pressure is good and i'm getting fire to the plug wires. i also reset the computer.

could it have fouled the plugs?


thanks,
sammy

 

never mind it almost fouled the plugs, but i got it started and i guess the iac is stuck wide open. its idleing at 2 grand
