Taking note that u like the idea too. Lol. Maybe if I can find a daily driver to use while I would attempt the project. Lol.

 

Need some help. PO303 code came up. Now before anyone says do some search I've done that but it don't help me and here is why.

Truck was running fine and I went to the car wash (not an automated one) I washed the truck (I didn't open the hood to wash engine) well after bout 5-8 minutes I got back in the truck and put it in drive (had the truck running the whole time I was washing it off) well when I pulled out of the bay the truck started jumping and and sputtering. Easiest way to describe how it sounds is like a helicopter when I give it gas. Also at stop lights and such its acting like its missing. It's jumping acts like it has a lope to it. So again it brought up misfire cyc 3.

Any thoughts. Maybe somehow water has gotten into the cylinder maybe plug. Been running like this for 3 days now. Any suggestions or help. Thanks.

 

Sounds to me like a coil pack that had a bad boot and the water shorted it out causing the miss

 

thanks for the helpful advice. I do appreciate it. I am thinking wires plug or coil. Was just getting some other opinions and experience as well. I'll more then likely go for a cool pack tomorrow. Thanks again

 

No problem man sounds exactly like what my dad's 97 did the last time he lost a coil pack only thing is his check engine light didn't come off since the lights burnt out

 

For those of you sitting on the edge of your seat waiting to find out what was wrong with my truck LMAO

it was the coil pack. Went to pull a part pulled one and replaced mine. It's running smoother then ever.

Also got me a set of wires and new plugs. Will replace all that Monday and oil change.

 

Glad it was something easy man.

 

Same here. But still have the dang 1518 code. Has to do with the imrc module. Gotta fix that sometime.

 

Gald to hear it was what I thought it was which I figured it had to be something like that after water hit it

 

What's the best spark plug gap for the 4.2L ???
