Hello fellow Jeepers. 2004 LJ 4.0 42RLE. I have some issues that I've been tackling. So I have been battling a P0432 for a month. Replaced the oxygen sensor after the cat. Still having problems. I'll reset the code and it wills till comeback every couple of days. And tonight it threw a P0306 and the CEL blinked at me. And the engine started sputtering and almost died. It wouldn't go above 2500 rpm and it acted as if the governor was set to that. I shut it off and restarted and now it runs flawlessly. No codes currently and we floored it and it ran fine to 70 no problem. So what could be the cause of this? Thanks for your help. Justin
