My jaguar has the check engine light on, 2 weeks ago the same thing happened and I went to the mechanic and he told me it was a misfire in the cylinders, but the next day it went out by itself, now it turned on again, so I took it to the mechanic and he cleared the codes, but the light came on again, I don't know if anyones knows what may be causing the misfire

You be in the wrong area.

The F Pace Tech Section, down the Home Page a tad, is where this needs to be.

Norri will se this when his coffee has him firing on all cylinders, and move it for you.
