Coil output would be the same either way as long as the dwell was increased for the stock wiring as noted in one of my earlier posts.
Mr Fred, you bring up an interesting point. I'm troubleshooting an ignition issue that only shows up once the car is fully warmed up and been driving for a while. Until that point, everything runs flawlessly. When it acts up, the car sputters all through the rpm range and is extremely sluggish. I can smell gas and it seems to be a cylinder mis-fire or no-fire.
My car was tuned on stock coils and a few months ago I upgraded to the Denso COP and haven't touched the tune. My plugs are stock and all gapped at .020" Should I start with increasing the dwell time slightly as you've mentioned in this thread? Do you have any other suggestions? Thanks.
