If it is a 1990 or 1991 3.6L it has one 02 three wire sensor very easy to get at and do between the two cats in the open or buy a universal kit and splice one on for half the price. It is a must have to get ride of the engine pulses the v8's commonaly have when driving. If it is a 1992-94 4.2 I'm almost sure they have two 02 sensors. I have 3.6
Yes, only one on the 3.6. But its not always easy to replace it. On my car the sensor was stuck, so I had to remove the x-pipe to be able to use tools big (long) enough. If you can lift your car very high, this is of course not a problem. Removing the x-pipe was not so funny.....;(
Thanks to everyone. I've changed the single oxygen sensor of my V8 3.6. In my car is quite easy because it has a manual 5-speed gearbox and the exhaust box it quite diferent from cars that have an auto gearbox. I solved the engine problems. Bye. Nicola
