RE: Plug Readings
Turbo54, are you sure that's not the other way around?
Rhubarb, You are correct sir...no FI...no PCIII.
I'm pretty sure I put new plugs in last spring, so they've got about 10K miles on 'em. Is that normal? I do believe that is the recommended time to replace plugs.
My Jeep's been running pretty rough lately, not sure if it's because it's winter or because the Jeep has 293K miles, but I decided to do a compression test on it. Wyou should've seen how worn those plugs were. The gap is supposed to be .035" but these had worn to .050" to .060"!
