I have a V6 02 f150, and I recently went through a little mud, and took my truck to the carwash today, I left my truck running, while i sprayed out the engine bay, and the truck ran fine for about 20 miles. Then whenever i pressed the throttle, suddenly the truck would shake bad, and felt like it was misfiring. But my service engine light never came on.

I belive that water leaked into where the spark plugs are housed, and was wondering if anyone knows how the remove the water without much effort. Or if i am completely wrong

Thanks

 

Same sorta thing happened to my 93 F-250 with the 5.8. I went through a creek and it did fine for a few miles and then it shook when you pressed the gas too much. It was a 5 speed though so I popped the clutch and that seemed to fix it because it worked fine after that. Maybe leave the hood open so it can get good and dried out in there? Sorry if i'm no help.

 

If you're as unlucky as I was running through some mud and about a foot of water in my '01 5.4 4x4, you'll end up removing the fuel rail, coil packs, and spark plug boots (just dont remove the plugs) then you can use an air compressor to blow the water out of the boots and out of the heads where the spark plugs are sitting deep in the heads. No amount of under-hood heat from driving around a couple of days would dry them out. Don't forget to wrap the injectors with some plastic wrap and maybe some rubber bands to keep dirt and water out of them. The spark plugs by the fire wall are a real to get to but just have patience. It's cheaper than having a service tech do it for you.
Good luck.

 

Try blowing them out with an air gun. Also, I would pull a plug wire a time and use silicone for better connectivity, and protection from moisture.
