[QUOTE="Genesiss, post: 443416, member: 22628"] Hello everyone, I just purchased a lifted 2008 jeep and discovered very quickly it had major issues. My symptoms point to a lot of possibilities. To start, I have a p0016 error code. Replaced cam, crank and temperature sensors. Tried to clear the code and it came right back. I noticed very quickly that I had minimal acceleration and zero uphill torque and it got worse every time I would try to use it. On the last trip I limped it to the mechanics shop at 10-20mph and after only 5 miles the catalytic converts were both cherry red and smelled like hot metal. The engine has 190,000 miles on it. My first thought was that it’s the timing chain and it jumped a tooth and it’s dumping fuel into the cat causing the cherry red hot symptom. Can I get some opinions? Most likely the chain needs replaced but are the cats the reason for the sluggish behavior or is it the timing chain? Can the timing chain cause fuel to go unburned to the cats? Debating just buying a rebuilt engine then wasting money chasing issues in a high mileage engine. [/QUOTE]
