So I was driving home from work today and for the first time my car started shaking pretty good for a couple seconds with the check engine light on.
It seems ok now (at this moment anyways) but my code reader pulled off cylinder 4 misfire.
Tomorrow I plan to pull off the coil that fires up cylinder 1 and 4 and test the ohms as per the factory service manual to see if it needs replacing, however I just have one question:
If a coil did go bad, wouldn't it throw two codes? One for each cylinder it's attached to? Since my car only through one code, should I assume its something other than the coil?
Just wondering where I should start with this.
