I generally get the stock plugs either way, I don't fancy it too important since I'm not revving high, but that's a bit half-butted of me,  |
From what I looked-up, the heat seems to be the culprit here. Burning oil is also a possibility, but not entirely likely since it doesn't loose much between changes.
For what it's worth, I guess "Heat Ranges" aren't really considered on modern, fuel-injected vehicles -- the difference is the gap.
I went with a
wider gap this time. Call me "half-butted" as well
, but I don't rev higher than 3-grand, and rarely (if ever), recall detonation issues. The rationale is that more spark area is available for increased combustion. It runs smoothly -- I guess the drawback of a wide gap is a possible misfire. We'll see.
But alas, the cover and gasket is back on and new plugs/wires are installed. No more stinky oil leaks.
Side effect: odd transmission behavior -- it's hesitant to shift to 3rd when I lift the throttle at the usual spot (2300 RPM). It's probably the TCM adjusting to different loads(?) 4th to TC lockup is fine tho.
Should I reset the ECU? I know it's recommended, but I worry about that darn hill-logic transmission control unit. The fuzzy logic seems to learn my driving style and I don't want to lose that. It could be a good thing to start fresh?
(oh, and I plan to replace the K&N cone with a standard OEM paper cone filter). More on that laters...
