2g misfiring...

[res7bequ]

well this morning i started up the car and felt it missing a little bit... after checking wires one of em was unplugged, guessing ### ppl are always messing with my car, after i plugged it in it was still missing and now it sounds weird and when the boost usually comes in it vibrates like mad and gets loud. anyone have any guesses on whats wrong? -thanks, Elias

Pull the plugs. The one that didn't have the wire pluged probaly went bad.

Was it driven while misfiring? You may want to check your spark plugs.

I changed the plugs with brand new ones but still misfires

Are you doing the compression test with the car warmed up? Service manual says ~212.

You could also add a tablespoon of oil to cylinder do and re-do the test. I think if it goes up, it's rings but if it doesn't, valves. Could be the other way around, I always get it mixed up.

yea i did the oil thing and it held like 65ish. the others are holding like 185

I'd get a leakdown test done.
