Okay, sent my son off to Ft Campbell 101st with his 2008 Jeep Jk. Had it running well.
He, as a young kid not focused, did little or no maintenance. Says “Dad I bought a used Ford Ranger, the Jeep just doesn’t run well”.
I get it transported home.
Muffler is rusted half off. It’s now banging around, slid off the Cat Y pipe but not before pulling and yanking the cats loose from the exhaust manifold.
1. I replaced missing cat to manifold in driver side, and tightened cat y pipe.
2. Tune up, new plugs, wires and Mopar Coil. Wow, 4 plug wasted, all of them were wow, 4 worse.
3. oil change (quart + low argh)
He drove it a lot, said yes it was blinding CEL you name it, so who knows. I know it needed the plugs/wires/coil.
now I don’t want to throw parts.
I drove it, Cats aren’t connected to exhaust and new muffler yet, but it is Misfiring big time, blam bam bam
So, trying to get a good idea of what all this can be and best order of ops
1. With all the misfires, and Cats disconnected some, they may be blown. How do I check?
2. O2 sensors?!! I’m not getting a code for them?
3. I don’t have compression tester, but is this a test I need to run here?
any thoughts, I’m exhausted with fixing this Jeep every time he’s away and I see it. Last time had to get a new Intake Manifold, the sensor the PO must have cracked installed temp sensor and JB welded and it gave. Super pissed.
He hasn’t rotated expensive BFG 35” MT and I can see the fronts have worn bad, argh.
Any organized suggestions appreciated.
