OK so I did a tune up about 1-2,000 miles ago. All was well. replaced cap/rotor/plugs&wires. For the last 500 mi or so has been rough at idle, not stalling but a little rough that you can feel. It is a little noticeable in the exhaust, vibration. I then read the forums and saw that Champion Platinum plugs sometime cause an issue! I used the 7304's. I also then realized that the GAP (pregap) was .45 and not .35 - so I re-gapped to .35. I check the vacuum lines and replaced a few that were marginal. I still have the rough idle. I added some injector cleaner since I did come very CLOSE to running out of gas about 3-4 weeks ago (fuel gauge was wrong). (thinking sludge mucked up the injectors). So far no luck. I am attaching the pics of the plug before re-gapping. Other than some carbon on the insulator I think they look normal ? Some feedback would be cool to see if I am on base here.
Is my best bet to go back to copper Champions ?
