So yesterday driving back from Washington my check engine light came on and had it checked out at auto zone. I don't remember the code number but I had 3 cylinder misfires and a random misfire. I already changed the spark plugs but the check engine light comes back on. Any ideas on what else it can be?

Would anyone be able to let me check their coil packs really quick?

Junior, Adam just went through the same thing, check out his thread here;

You should just be able to swap cylinder's and see if it's still doing it when you swap the other good ones you have. Hope this helps.

Thanks Ira, i read up on it, tried all methods and still my engine still has issues. Tried fuel treatment, changing coils, changing spark plugs and when my car idles it shakes pretty bad. Sucks that i cant drive

that does not sounds good. did you do a compression test, yet? maybe a valve not sealing properly.

Like Ira said, this happened to me a few weeks back. My advice would be to take your car to Forged and get a valve adjustment so they can look and see if anything under the head is going on. To me it was worth it because it prevented me from eventually dropping a valve and ruining my engine. Good luck man, and let us know what the issue ends up being.

Im considering taking it to forged but i would need it towed there. I do hear cracking in the exhaust and bad idle, even when i try driving the engine seems to give out. Plus, i got a valve adjustment not too long ago so i doubt it could be that.

looks like the engine need attention and major check up. if i were you, dont drive the car anymore and i would get it towed to trackforged . it could be anything like bent valves, worn down valve guides, cracked retainers or maybe your injectors are bad. By the way who did your valve adj?

Forged did them around 3 months ago.

Damn son. Yeah like everyone else is saying. I would get that bad boy to forged ASAP. You wanna prevent as much harm as you can.
