[QUOTE="wfooshee, post: 744483, member: 6354"] TPS isn't the problem if it's just rough idle. Mine idles rather poorly, and I had a plug that would foul within a few days after replacement. I've gotten where I "rotate" my plugs; once in a while swap #4 with another cylinder's plug, so the fouled plug gets cleaned in another cylinder, and #4 gets a clean plug every so often. I think I have an injector that runs richer than it's supposed to. I also replaced one of my coils when I found some kind of residue on the plug wire coming out of it, which helped. Like yours, idle is not exactly silky, seems to miss once in a while, but under power it [I]is[/I] smooth and strong, so I haven't really been worried about it. I also know that I'm overdue for a valve check. Straight-cut gears will whine. All the gears in the transmission are straight-cut, as are the gears driving the balancers on each side of the crankshaft. [/QUOTE]
