I have a 99 Xj I picked up with a blown motor. Got a motor from a 91, swapped it over. Then had the heel sit for about 5 months, put fresh oil in it, new plugs, wires cap n rotor, new TPS and new IAC. Also have a throttle spacer on it there 4.0l. When I stated her up she ran fine then started to spotter when hot, then when tune up n new sensor came in, though also because the battery was dead for so long. Then had her running did idle on her own had to hold the throttle for a little till it was good. Then in gear stalled out. Just put a new exhaust and going to install new o2 sensors this weekend. Any help with this horrible idle or am o still in relearn since I haven't drove yet.
