Hey everyone I need some help. I recently acquired a 1988 xj with the 2.5L throttle body injected 4 banger. It had the motor rebuilt before I bought it and only has 2200 miles on the rebuild. For some reason it has a hard time staying alive while idling. Some how it manages to keep running but the RPM's drop low and the motor shutters then the RPMs come back up and then it repeats. Also I have noticed while driving I can hit the throttle and get almost no response from it until the throttle is almost floored. I am thinking maybe the IAC or the O2 sensor, I also thought maybe the Cat is clogged up. If anyone has any ideas of what it may be or how to go about diagnosing this issue any input would be greatly appreciated
