[QUOTE="tobyw, post: 1566116, member: 16413"] Chasing a problem on my 2004 LJ that's got the 4.0L/42RLE automatic... About a year ago, after a long loose/rocky climb in the Naches area on a particularly warm summer day, the engine quit while idling at the top of the hill waiting for my wheeling buddy, and it would not restart for about 15 minutes. Ever since that day, the Jeep has exhibited a slight stumble/shudder at idle, is down on power and fuel economy, and has a notably different exhaust note, almost sounding labored if that makes any sense. One other thing I've noticed is that there is no longer any change in RPM when I shift between Park and Drive/Reverse. Usually idle RPM is slightly higher than when in gear and there is a small lurch, but there is zero change. There is no CEL, spark plugs look fine, and I replaced the TPS just because I had one on the shelf and it made no difference. I'd greatly appreciate any thoughts or input on what to check or look for? [/QUOTE]
