Earlier in the month my car was stumbleing and I was getting misfire codes in cylinder 1.
I found a bad coil in 1 that had a clip issue. So, I cylinder 1 and two to troubleshoot and there was then a misfire code being thrown in cylinder 2.
Next, misfire kept happening in the 2nd cylinder. With the new plug so I swaped it to cylinder 3.
The car then ran great for about a week but would randomly "rev" in idle.
Now I have new misfire codes on 1 & 4.
The new coil is in cylinder 3.
Anyone have any sugguestions? I'm at a loss for words.
