I have a opportunity to buy a 01 XJ 4.0 4x4 with 107k miles on it. The motor is pretty much gone on it. My worry is when I checked the undercarriage I noticed that the cat was gone and replaced with a test pipe, and so where the other 2 cats that go on the exhaust manifold. Supposedly it's has 4 o2 sensors but I only found 3 of them and those where by the motor, the other one seems to be none existent?? The owner say there was no cel but with it actually not running its hard to take his word on it. The cats I know can replace but not being able to locate the 4th 02 sensor worries me I was thinking since I have to pull the motor anyway, swap out the wire harness, and go back to regular emissions. Anybody have any thoughts on this?
