Re: Spark Plugs
well, with conflicting reports like that, just take 'em off every 10k and look at them. if there is excess carbon buildup(engine running rich), or if they look burnt(engine running lean) you know you have some other problems too.
anyways, just check the plugs for wear, if they are dirty clean them, and if they are good, put 'em back in. if the end of the electrode is rounded, or the plug is cracked anywhere, it needs to be replaced.
Oh, and re-gap them too, while you have them out, might as well, right?
