Not trying to freak you out, but watch your oil level. When cats break apart they sometimes have tiny fragments that can literally get sucked back into the cylinders.
It's not a guarantee, but has happened to others.
I just got this car to drive for a little while. From what I've heard of this vehicle, the SES light has been on at around 80k, it's currently at 165k. This thing is beat up and has a host of problems. So far, I've diagnosed:
- TPMS lights on with C1706 and C1724. Whoever did the first tire change probably broke the OEM sensors because it's just a regular rubber valve stem.
- Seatbelt light is on with a B1086.
- All the wires for the rear driver side door harness were severed. The two wires for the belt pretensioner are included in this harness. I spliced them back together but the B1086 code still exists. I checked the TSB for this and the vin is within the range but Nissan says this vehicle not eligible. It's a 2006 Titan King Cab.
- The steering input shaft into the rack & pinion is leaking.
- I'm pretty sure all the fluids on this vehicle are original aside from the motor oil. Planning on doing the tranny and diff fluids soon.
- Parking brake does not engage at all. It clicks but has no resistance and it goes pretty much to the floor.
- Front struts and rear shocks need to be replaced soon.
As someone who enjoys working on cars, I've done the following maintenance:
- Replaced the oil cooler gasket which was causing an oil leak.
- Replaced coolant.
- Replaced the belt tensioner, idler pulley and serpentine belt.
- Replaced the spark plugs with LFR5AIX11. I'm not sure if it has been done before because the ones I pulled out were LFR5AGP.
- Replaced both sides inner and outer tie rods.
- Replaced the power steering high pressure hose.
It's a long list but we tackling it 1 by 1. Here are some pics of what my scanner says about the TPMS
