Help
I have a 2003 jeep Cherokee laredo. I just recently rebuilt the heads, but I'm now having new issues. I have 2 codes coming up right now, but I'm not entirely sure they're not coming up due to another issue.
Anyways it currently will buck and kick out at 3,000 rpm, it's got a rough idle and regardless where the tachometer is reading, between 50 and 55 mph the entire car shakes as though the engine is getting ready to blow.
The coil pack is new, it was triggering codes for misfire in cylinders 1,3,5 and 6. Unplugged that and plugged it back in and no longer getting misfire codes. A current scan shows codes p0122 and p0442. Any ideas, I'm skeptical that the tps is out, I'm not seeming to have any of the typical symptoms of a bad tps?
