Could be a misfire too

 

It's def not a mid fire. Just rebuilt the whole top end lol. New everything. Things ya gotta do when ya blow both head gaskets lol.

 

Well it's been awhile since in here. Had some probs and was unable to get online. Anyway. Truck running good after the head gaskets and everything else that has been fixed. It was sitting for a good 3 months. Just started driving it again and had to replace both upper ball joints. Got rid of the clunk I heard. Also added some 6 inch round drive/fog lights. Wish I would have done that long ago. Only thing now is when it sits out in a heavy rain and I go to start it it will sudder under acceleration. Engine light starts flashing and then the smell of rotten eggs. The cats I know. But can't figure out where the water is gettin into the engine. So that is what I'm working on now. So if anyone actually like to get updates On this thread I finally got around to it. Srry for the very long time but it wasn't aviodable. A pic or two to follow soon



It needs a good cleaning. Will come after stops raining. . Lil nephew put the sticker on my truck. He thought It was funny. That's will be coming off asap. Also found some better mirrors and got rid of the flag style ones.

 

On my 5.4l I had a blown out o ring under intake plenum at heater hose v connection.my intake is plastic and the plastic holding o ring failed letting water into cyl 1. Replaced intake problem solved . hesitation stutter could be missing coil over plug I had that issue as well with same symptoms even rotten egg smell and cel blinking. Replaced it fixed problem.

 

My leak in my hood that kept giving me misfires was around the spray nozzles. Easy to pop them out and put a little rubber gasket material to cure it.

 

Thanks for the help. I just done the whole top end. Had to replace head gaskets. I may take upper off again to check things out. I have a coil pack. Mine is the 4.2v6

 

Thanks for the tip I'll look into that. Appreciate it.

 

Is your intake plastic?

 

Sounds like you got real lucky, spraying fuel into cyl port.

 

I was talking about the spray nozzles to wash the windshield.
