Jaguar Xj6 vanden plas: Hey Richard, I have an issue with

Customer Question

I have an issue with a 1996 xj6 with the monitors setting.
The only ones that are setting are o2 heater monitoring and EGR monitoring. The car is not giving me any codes or a CEL.
While troubleshooting I changed the air filter, cleaned MAF, installed new plugs and gapped them to factory specs per service manual. I found one of the exhaust gaskets between the cats and manifolds leaking, changed them. I also changed one b1s2 o2 sensor as it was only giving me readings at wot. The throttle cable was also lose with a lot of slack so I adjusted it.
It's not my car and I've never driven an XJ6 so I'm not sure if it is down on power. It drives well on the highway, althou it will not break the tires loose from a standatill.

If this is an issue with getting the computer monitor to run and complete in some cases the procedure below will help with this.I have had to do this twice in some cases.If this is not what you are looking for here or if you need anything else let me know.

Once the engine is started, DO NOT turn the engine OFF for the remaining portion of the set procedure.
