Hey all, still unfamiliar with this 2.7L motor, and 'yotas in general, but a tune up is a tune up, right? I swapped the plugs, wires, and cleaned the MAF (didn't touch, sprayed with MAF cleaner only.) The last couple starts smelled pretty rich, so I just pulled the plugs and they're all sooty already. The plugs I swapped out were kinda grey. The new ones are definitely black - there's maybe 30 miles on 'em. I had the battery unplugged for a while, so I assume there was an ECU reset and it needs to relearn? Anyway, I regapped the plugs a bit wider than the .032 that Autozone recommended; I've read different gaps on the various online info for this motor.
No CEL though; am I just paranoid? The truck seems to run smooth and idles nice and low now, like 600-700 rpms.
