[QUOTE="hbar, post: 456332, member: 21924"] I replaced the oil cooler & both sensors on Friday. Within 30 miles all the codes cleared & all sensors were ready. Then today CEL came back on & at the same time did that thing where it won't rev beyond ~3500 RPM or upshift unless I let off the gas a little. Got home, checked the codes: Pending: P0420, P0520, and P06DD Confirmed: P0420 P06DD Permanent: P0420 P06DD The 520 & 06DD were classified as permanent prior to replacing the oil cooler, so it's frustrating to have seen them clear and then come back. The 420 code is brand new. It's double frustrating because while I had the CEL off long enough to pass TX inspection, I am planning to sell this thing in the next few weeks (I prefer the TJ life) but selling with the CEL on is suboptimal. Any advice on these codes? [/QUOTE]
