I have a 04 jaguar xj8 that skips/runs rough when it heats up but runs great when it's cold for the first 10 minutes. A mechanic says it's the oxygen sensors causing the issue. Could oxygen sensors cause this problem?

Thanks for any help.

 

Possibly. But to be honest, you would be better off asking in the 2004 forum, not the 2009+ one, as people there may be better able to help.
