RE: i
yeah, I'm back in jeepz land. I don't remember the last time I was here. My wife and I had a daughter last may. That's consumed much of my time. Anyway, let's get down to business:
I got motor problems. When the motor is at operating temp (~195*) and I'm at highway speeds, the spark-knock (or pinging) starts getting bad around 2500 rpms. If I don't let off the gas a little, the motor starts... decelerating with a symptom I like to call de-compression. It's like the motor is combusting the fuel/air mix below the piston, but then combusts again above it causing my motor to slow down with the gas pedal, rather than speed up. I can only do 55. While I'm not a speed demon, I would like to at least be able to go 65. I have a feeling it's due to blow-by because after a compression check, my #3 cylinder had a very low compression.
Any ideas (other than: change the oil, change the plugs)?
