Hi everybody. I have a 1998 Jeep Wrangler 2.5L manual transmission. When it is cold outside and I am coming to a stop my foot is on the clutch and I allow my vehicle to coast. When I do this my RPM's drop almost to a stall until I come to a complete stop and they jump back up again. This was the case until recently it is now starting to stall occasionally. Any ideas on this situation would be greatly appreciated. The only thing that has me stumped is why the RPM's return to normal when the vehicle comes to a stop.:crash::banghead:

Does it also do it when you put it in Neutral and let the clutch go?
If so, it sounds like the clutch fan may be locked up (failed) and is causing this. I don't have the 4 cyl, so I can't say if the fan is the same, but maybe someone else can.

Pull the box off your throttle body and clean the Idle air controller motor. Just went through this on the ZJ this weekend. Fixed it some but if I get a warmer day I'll pull the IAC and clean it on the bench.

It stalls occasionally when I put it in neutral and let the clutch go but not all the time. I have tried different scenarios with the clutch but it doesn't seem to be related. If you are talking about the cooling clutch fan then that may explain why my temperature gauge hovers closer to the second line as opposed to the 210 degree line.

Richp in response to your reply I will try that suggestion as well. There are some nice days coming up so I will take advantage of them and give it a try.
