that's what I figured. I went back to the stock gap. Since December I did this coil mod my car has given me the p0420 engine light. I am hoping it goes away. Next time it comes on I am going to have my guy look at it.I did the same a few months ago. Stock car stock gap.
I don't know. Soon as I did this I started throwing a p0420 a month later. I put the gap back to 0.034 stock. Should I go lower?I have a hard time seeing the connection between P0420 and plugs if there are no other problems, but your gap is too big anyway so I would reduce it first.
