Isuzu Trooper weird Problem

[topdesigner]

Hey I have an 98 isuzu trooper, whenever it is cold outside my car idles very high upon warming up. After it is warm I have to cut it off and count to 30 seconds and I will start it up and it runs fine. Sometimes it stalls on me also. I did find a small leak around the fuel injector it seems like it is sucking air, would this be the cause of the wierd problem. I checked for intake leaks and Im 100% sure I dont have one. Could it be the MAF or O2 sensors. Any suggestions will be appreciated.

THanks

I'd start by having your OBD-II ECM checked for any error codes and see if that points in some direction. Most parts stores will do it for free.
