Carolina Comanche Posted June 28, 2009 Share Posted June 28, 2009 First off I wanna say I love this place! Up until now, I have found an answer to every problem I have had on here. This time time I can't seem to find it. I've got an 89 4WD 4.0. It does fine around town but on longer drives (10-15 minutes) it idles down and shuts off when you come to a stop. When you go to start it back up it's kinda hard to start and theres a strong smell of gas like its getting flooded. After talking to a mechanic buddy of mine over the phone, we kinda thought it was the IAC. I replaced it since it was a fairly inexpensive and easy replacement but after the test drive this morning, it didn't work. From the other topics I've looked at I was thinking either EGR or TPS but I don't get why it would do fine driving around town and not on longer drives. Opinions? Suggestions? :help: Link to comment Share on other sites More sharing options...
64 Cheyenne Posted June 29, 2009 Share Posted June 29, 2009 I think it's losing spark. I'd check the crank position sensor. My friends XJ did the same thing, when it got hot, the insulation going to the CPS was getting hot and shorting against the exhaust manifold.

Carolina Comanche Posted June 29, 2009 Author Share Posted June 29, 2009 Ok, I got her fixed now. It was the EGR. $112 for a new one?? I don't think so...I just bypassed it totally. Man, I love NC emissions! Link to comment Share on other sites More sharing options...
