I have a misfire, it is only noticeable at idle and at a constant rev at 1700-1800 rpm. At WOT there is no sign of weakness or drop of power, i have had the miss for a very long time never had an issue and still don't have any problems. I just want to fix it. It is not throwing any codes, plugs have been changed, COPS seem to be fine. Ran sea foam, and injector cleaner through it still have it. I ran 13.6 at the track and thinking that my car may not be running at its full potential. Any help would be appreciated!
