I'm glad I bought my Cherokee and I'm even more glad that this site is available for help. I was gonna ask another stupid question but I think I found the answer. My Jeep has been idling pretty low when I start it; around the 200-400 RPM range and dips way down when the throttle is hit and released; such as backing up in reverse (it dies). So I looked a bit and was thinking TPS. Well, other people had the same issue, so that's something I'll be checking tomorrow And hopefully adjusting. This is the time when I really miss Autozone though. All we have here is a NAPA and Checker.
