C32 problems :( help?
I was driving my car as usual, got to a light, and on idle the car started shaking , I started to pull it over and on acceleration, the car would shake violently and the CEL came on. Long story short, I got the car scanned and cylinders 1,3,5 were misfiring. Error code P0300.
So this is what I'm thinking it could be:
Coilpacks or wires
Cats
Vacuum leak
My question is, which is most likely the case? And is there a way to check to see if the coilpacks are bad, and if so, which ones? I just got the Eurocharged tune, and the next day it happened. Eurocharged, with their amazing customer service, checked the tune for me, and confirmed that wasn't the issue. So what I'm thinking is that the coilpacks were already going bad, and the tune just accelerated the problem.
Any help is appreciated!
