I have a 2000 xkr I recently have the oil changed, coil packs replaced,front o2 sensor replace, fuel filter and spark plugs changed then the engine light came on and won’t go of. Help!!

 

Hendu,

After all your work, it’s bad to hear that the car’s CEL has come on.

To see what the problem is, you’ll need to have the OBD2 read to get the DTC codes that is causing the CEL. If you don’t have one, any garage can quickly do this for minimal cost. You can buy one as the simple readers are cheap and easy to get but you’ll need the Jag specific table for the Pxxxx codes. Don’t trust what generic readers say esp. as you have a Gen2 X100.

Any trouble when you drive the car? Misfires, limited performance etc?

Best guess at at the moment is your replacement O2 sensor is wrong as some members have said these cheap parts are wrong as the Jag sensor has a preheat element.
