"New" 02 kj owner with concern.
I'm new to the Jeep/forum scene and have a possible problem. I just purchased an 02 kj 3.7 auto, with 99,000+ miles. Question is I just broke 100k and started to notice a "puff puff" sound running throughout the exhaust, speeds up as I accelerate, although doesn't seem to do it until it's at full operating temp. I've tried to google it, youtube it, and search forums, and it's definitely NOT a tapping or any kind of metallic sound. Been very nervous lately coming across all these blown 3.7 engine stories. Thanks in advance!
