Some history - replaced many up and downstream sensors. 2 caty converters (one was a recall) Usually Jeep runs rough - 1997 Wrangler Jeep SE - but it seems to be running pretty good and not running through the gas worse than it normally does. The engine code that mattered was a 72 - catalyst efficency below required level. So tired of this......HELP!:banghead:
