MY truck seems to have this random, whenever it wants to just die... then as its rolling to a stop it starts or like today it wouldnt start for a few minutes, then i try it one last time and it cranks over and over then starts..

seems to do it the most while I'm accelerating or letting off the gas..

Tranny hitting the wrong gear?

I know its not a ton of info, no codes, no lights, runs fine the rest of the time.

I had the battery unhooked yesterday.

Any ideas?

 

get a V8! hhaha

 

^^^x2

 

mine does it every once in a while or sometimes it will do it right after i fill up....its weird

 

ha, forget the V8, not worth it.

when it happened today i was low on fuel, but no light yet.

 

Fuel pump?? Sending unit?? How's your filter??



My IAC is clogged again......at startup, she fires right up, high idle, isle goes way down, then starts to die....i gotta blip the throttle to keep her running. once she running for a few minutes, she's good to go.

Crazy ford engines.

 

sounds like an iac or the fuel pump is takin a crap ...

 

looks like the perfect time to swap in old reliable!















the vulcan 3.0!

 

Sometmes I wish I had the old reliable 3.slow.

 

Yeah and sometimes i wish i had a 4cyl car that got 30mpg... but that sure as hell will never happen!

 

i have a 4cyl truck that gets like 18mpg.

 

thats terrible, i get 14 in the city if i drive nice.

 

mine did it sometimes when i had the superchip in. do you still have a plug in chip?

might want to try cleaning the contacts and making sure the chip doesnt move

 

yeah i still have one, its possible, i had that problem when i just got the chip, might pull it out this weekend and check it out.

 

the iac effects the truck when accelerating?

 

I changed the filter 20k ago, I suppose i could change it again.

Unless i dont understand the full effects of the IAC im not sure why it would be the issue.

 

mine does something similar, in the morning on the first startup of the day.. itll crank but it nearly dies, and i give a little gas and its fine the rest of the day.. o well, it still works!!

 

Fuel Pump sounds like a legitimate issue.

You might want to stick your head by the tank and see if you can smell any fumes.

I doubt its the IAC.

 

I would check the battery cables. I had a bad one on a motorcycle and it would cause the bike to die on heavy acceleration and sharp bumps. It had a crack in the cable under the double insulation. Took 3 days to find.
Another motorcycle would die at weird times and it turned out to be a bad computer that did not have any codes showing. They finally swapped out the computer with another to find it.

Check other connections on your wiring and for any wires lying where they shouldn't be. Near exhaust or have rubbed against something.

 

Ill check the wires and see whats up.

 

I get 22mpg and I have my foot in the gas alot.

 

It's your trucks way of telling you to get some crazy 4wd flex pics posted

 

My truck used to do it too, i did the throtle cable mod, and now it hasent happened for 6 months. could be worth a shot.

 

So does your throttle cable get held slightly more open at idle now? Raising your idle and keeping it from stalling?

 

Could be a TPS on its way out too Zach. MAF clean? May be a crankshaft or camshaft sensor glitch as well. I would definitely check the battery cables and the chip. Make sure your theft light doesnt flash when this problem occurs. It could be the chip is not making perfect contact and screwing with the PATS system. Seen them all before, just some ideas!
