I washed my engine with a power washer didn't spray it really hard cause I'd knew I'd break some thing. so I sprayed it from a good distance on my engine bay ever since around 1000 to 1600 rpms my car is very shakey when accelerating especially in 5th gear. No water is on my air filter either and after a day my car is dry I've been driving it quiet a while it should be driving normally I wash my engine a couple times before but usually runs fine after a day of drying.

maybe u wet a spark plug
Ah. I was checking my car and found a coil lose. Perhaps water got in. Would I need new spark plug to fix this or maybe let it dry?

Water in spark plug well. The detail guys do it to our lot cars all the time. Once u find the hole with water in it you can try blowing it out and dry it all off to see if it gets better. Otherwise it will need a new plug and coil for that cylinder.

Well I replaced all my spark plugs just now. And there it seemed a little better nothing was wet down there. Some were moist but I think cause of the goo stuff from the bottom of the coils. So it's probably my coil also I found my air filter not on it felt a little better though after all that put after I revved my car it died and then started up again.

Well, if it doesn't have a cel? I would use IDS and perform a power balance test to determine what cylinder is missing. Then swap coils with a good cylinder to see if the miss follows. I hope you used motorcraft spark plugs too. Have seen plenty of problems with using other brands. Ford uses a VERY picky ignition system.

Okay so figured it had to do with my idle wouldn't it be coil #1-#4? I have a lose coil my friend pulled the coil out with the screw in he said I need to get a bigger screw and rescrew it in so it won't be so loose causing it to misfire and shake and almost die after revving?

What was the code? You say in your previous post p0304 and call it number 8 misfire. But number 8 misfire would be p0308. Yes a loose coil would possibly cause a miss. All though I've seen coils not bolted down at all cause no problems.

There isn't a code. Ik it's been loose for a while and ran perfect but now in low rpms it just shakes and after I rev it wants to die some and my idles sound loopy. I was at a car met tonight a tuner guy got in my car reved it and saw it drop and said yeah what I thought your cars running rich and then I said I think I have bad coils so he said its probably coil #4 cause of my idle and look at #1-#4 and saw #1 loose pulled it right out and said there's your problem your only running on 7 cylinders!
