So when i warm up my truck in the morning i have no problem. But if i leave my truck in a parken lot for about 30mins ill start it back up and it has a bad misfire and the truck wants to die, but when i revd up the motor for a second it went away, Whats goin on it dos it a random and iv checked my plugs and intake and it just fine. any ideas

 

An injector partially stuck open would dump the remaining fuel in the fuel rail until the pressure went down.
With a cold engine, the fuel would have had time to evaporate and not cause a problem.
A warm engine, just shut down for a short time would have gas sitting in the intake causing too rich of a fuel/air mixture.

 

Mine does this occasionally.
Try some Injector cleaner, i recommend Lucas Oil. i do it about every 6 months, keeps them clean and lubricates the lifters.

 

You know that really sounds about right, cus i just put in some EFI cleaner about 2 days ago and it still acked up last light, but today i had no problem. So that must had been it, , And yep i always like to run that lucas even now and then

 

Are you talking about the regular lucas oil or do they make a fuel injector cleaner?

 

I get slightly better mileage running this stuff, but my truck idles better with it. I suggest getting a gal jug if you can find it, it has the best price.

yeah its good stuff. but today it did it again i went into town and left the truck for about 40min and i went to start and it had a really ruff idle like i had one dead cylinder, Should i try another bottler orrrrr whats next

 

How long has it been since you put the bottle in the tank?

I have a gallon of the stuff, and i have a little bottle to pour it into when i go to the gas station, its just easier that way, lol.

 

umm i think about a week
