Fuel Issue

USMC302 · 07-20-2007, 02:32 PM

Sounds like fuel starvation maybe, throw a new fuel filter in there and double check the timing. What is your Fuel pressure set at right now? Your 14 degrees advanced in timing is with the spout connector out right? When it does it next time, kill the engine immeditely and coast over ot the side of the road, pull some plugs, see if the're dry or wet....Have you tried pulling any codes yet? That would REALLY help out. I've also mentioned checking the TPS voltage again and letting us know what it is, I also suggested cleaning the mass air meter, are you trying any of these?

replaced two of the fuel filters, the one in the tank, and outside. replaced the fuel filter itself. replaced the fuel lines running from the tank to the outside fuel filter. timing is right on 14 degrees, have a perminent mark to show the correct position. tried using a new mass air meter. still no luck. not sure about the tps voltage yet. i think if the tps sensor was an issue i would have a problem all the time at certain rpms? will check though when i can get a tester. spark plugs are new and starting, idling, and 99% of the time everything seems fine. i think the issue would occur all of the time if the spark plugs were and issue, but i will check for moisture when i get a chance. question, i though at first the issue was heat related, but in the morning the engine is still cold when i have problems. it almost seems more like the amount of time from starting the car to getting a few minutes down the road, so the question is how could time be related. just don't know at this point.:

update: the car was bogging down a few minutes after starting down the road and i stalled out at a stop sign. when i turned the motor back on it ran perfect, so i tried this again several times. each i was going somewhere i waited until the car started running bad and cut the engine. i then immediately started the car back up and it ran perfect until i got a few minutes down the road and the car bogged down again. i seems that the issue occurs 5-10 mins after starting the car. someone suggested that there might be a problem with the computer? again, i'm not sure?
