So I just got an 03 Termi and it ran fine on the 80 mile drive home from it's old owner. Being me, I had to change out the plugs and I'm glad I did because it had the stock plugs in the passenger side bank and different plugs on the driver's side. Here's my problem though - since I changed out the plugs, I now have a pending code that comes and goes for cylinder #6 misfire (p0306). I already swapped coils to a different cylinder to rule it out and the problem did not follow the coil. I've tried a few different gaps already - started with .041, then .035 and now .032. I still have the pending code. I can't help but think it's the new plugs. They're NGK TR6's, btw. I need to figure this out because I need to pass smog and get my tags already. I'm about to go buy the TR6ix's because I read that a lot of people have issues with TR6's. I'm guessing that it has something to do with each engine being hand built. I had no codes beforehand, even though the old plugs were gapped pretty big and were pretty old. I'm using Dash Command to follow the codes and see what's going on. Anyone have any ideas?
