UPDATE: Still dealing with the same low engine power under load (hills especially at highway speeds) Got a Bluedriver scanner and ran through everything that was supported for an xj. The only thing coming back abnormal to me is my short term fuel trim never changes at all during a drive...

Reason I replaced and looked at the cat first was from all the oil in the pipe from the previously blown motor. Lots of burn off after the swap from the pipe.

Did a real time scan and no irregularities with sensors showed up. Checked timing two nights ago. What has popped up as of yesterday was the dreaded vibration from my TQ converter failing along with new shifting issues. Strange there have been no codes or anything. But I’m getting the shudder...

Correct!! Also checked fuel pressure last night and it’s at 51psi when revving rpm’s. I’m totally stumped.

Yeah I was looking at a cut away of the s10 and it looks like only some massive debris like a shop rag could clog it😂 I ran the downstream o2 sensor removed and not much improvement if any. Could slowly failing injectors cause a significant loss of power without throwing a code? I’m going sto...

That’s what I was thinking with the extra heat and lower too speed as a potential cause also. I looked at the Cat and it wasn’t great but I’ve seen a lot worse so I dismissed the muffler. I’m running a flow master super 10. Is it worth trying some kinda cleaner or just get a new one?

Yeah I have

Hey all. Got a 98 xj sport auto I recently did a 98 tj sport swap with. Xj has 183k and tj motor is 103k No cel Idle is 720-740pm Temps haven’t climbed more that 215 under hard load and generally sitting at 200-210 I’m having big issues on highway speed hills with very low power. On big hills...

Hey y’all. I got a 98 xj sport I just did a 98 TJ 4.0 swap with that has 103k on the new motor. Everything went smooth but I’m encountering a fast off/on drop in power or a sputter under load during low rpms (2k and 20mph and under)on my last 2 tests up a fire road. Stop start hard acceleration...
