I installed pre-gapped Denso ITV22 spark plugs about a month ago. Friday my check engine light came and stayed on for about 30 miles. I had the code checked and it was "P0300 Random misfire". It did not indicate which cylinder. I had noticed after I installed my exhaust a slight miss in the mornings when I would start her, but didn't think much about it. The stock exhaust was too quiet to hear. I started to really listen after I pulled the error code. Today I was listening after a cold start and noticed that it misfires until the engine warms up and then seems to go away. After getting home from work (45 minute drive) I listened for a couple minutes and didn't hear any misses.
Is this an issue with the Denso plugs on my non-tuned EB? Should I roll back to the stock plugs?
