Paid my little brother to wash my truck for me and he told me he just hosed off the engine after I realized it was running rough.. It smells weird now too after its running.. What could this be? Coil packs? Plugs? I have no idea. Any help appreciated.

Lots of people have problems woth coils when they wash their engine bays. I sprayed the hell out of mine today and it runs fine and always has when ive washed it so idk what it could be for sure man

I was one of those guys... I washed my engine bay out and the very next day 2 coil packs blew.

Your supposed to leave the engine running while washin it. I've always done this and never had problems

Ive always turned mine off while doing it and havent had any problems. Idk though I could just be lucky.

oh okay, well thats just what I've always heard and been told. I just let it run wash it and after im done washing the engine bay I let it run for alittle while long to dry off some.

Yeah ive been told to leave it running too. Ive also been told to let it sit and get cold so u dont crack the block but that seems like itll never happen. I just dont spray directly onto the coils for a long time. I keep the wand moving.

I've been told never to pressure wash any anyone up lose, cause you can blow out seals and wires if your not carefull

Did you get any water doen in the spark plug holes? It could be shorting out the plugs.

I would never wash my engine bay!

I do with a rag, and it usually doesn't have much water on it. But then again, boost is what lets you know its weak and/or going out. Our coils in these trucks are very finicky, let alone how far our spark plugs are down in our heads to let water out.
