i keep getting codes p0304,305,306(cylinder 4,5,6 misfire) and the car is running rough when it idles. i washed the engine off yesterday with a pressure washer(ok so i'm an idiot) and every since then the car has not run very well
i've replaced plugs and wires and i took the iac valve off and cleaned it up. anybody have any ideas

Unclear from your post as to whether idle and misfire problems arose only after your power wash. If so, borrowing fiance's hair dryer and applying hot air to ignition and engine wiring (including coil pack) and ensuring spark plug recesses are free of water seems a place to start.

Same thing happened to me. After having no luck with a hair dryer, I went out and bought new plug wires. Helped for a couple days the the miss returned. Today the mechanic said that two plugs were cracked and that my wires, although new, were defective. So buying those again too. If it happens again, I'll be sure its the coil pack.

i may also end up replacing the coil pack at like $72.00. the miss is getting a little better so i'm going to give it a couple of days and see if it goes away.

well the car is on it's way to the dealership for all of the misfires and a whining noise in the engine. hopefully the extended warranty will kick in.
