Hey guys how's it going. I've been having trouble getting my xj to run right. It just dies one day driving down the road. It would start but stumble and when I gave it gas it would bog down. I have replaced the cps, tps, iac, and the map sensor. It will start up fine and run for maybe 10 seconds then the idle gradually goes down then it just dies. When I give it gas it still bogs down below 2000 rpms. Anything above that it's fine. Please if anyone has any suggestions give them. I'm stumped and have never had this happen before. Thanks jeff
