4.0 keeps stalling out at idle (1998 XJ)
1998 XJ 4.0 Automatic 108xxx miles
After mudding last Sat. my jeep (1998 xj) will start and idle fine but after I give it some gas it goes below idle and dies. I changes plugs, wire, cap and rotor today. I also checked for error codes using the key and holding the odomiter, it goes throught the 000000-999999 but then shows no codes. I was going to put in a new throttle position sensor today but was wondering if anyone else has had this problem and could give some insight before I put more $$$ into the jeep.
edit: I also removed the cat today and the sensor behind it. the cat was shot and this problem existed before I removed the cat.
