i just got back from a 9 hours of driving across the state and my truck ran perfect when i got home last night, even when i drove to school this morning. but when i left school it wouldnt start unless i held the gas while starting it and it wont even stay running i tried driving it for about 15 min and it still does it i dont know why it would be doing this. just changed plugs and wire last months, and new EGR. has this happened to anyone? if so what do i do?

 

how could it take you 9 hours to drive across FL?

How many miles on your truck, year, when did you last change fuel filter? H20 in your gas? try dumping a can of "heet" in your tank.

 

fox,

Check for vacuum leaks. Check the hoses going into the throttle body and Elbow. That means the valve cover breather on the driver side, the PCV on the passenger side, the IAC piping and all the clamps from the MAF back to the TB. What mods do you have and what engine? If the EGR gasket was not replaced it may be leaking there too. Check the vacuum hoses going to the EGR for cracks and make sure they are connected properly and not leaking.

fuel filter changed last month 97 4.6L

 

ok what is going on i just let it sit for 45 min. and went out and did the same thing the first time then i tried again and it stayed running didnt find and leaks in the lines, and no mods. also when i was looking at the lower pulley in the egine possible the crank, it looked as if it may not have been completely centered(a slight wobble) is this normal?

 

lol thats from Palm Harbor to Daytona to Melbourne and back lol I guess this is what i get for trying to surf in 40 degree weather
