Hi people,
Today I have had my first problem with my scooby.
She threw fault code p0546 at me while driving home, i've read that is the egt sensor.
But on my way home, put my foot down a little out a junction and she started misfiring as the boost built up. Is this normal with the egt sensor?
Very occasionally if given the full shoe out of a junction, she will misfire for a short while but return back to normal leaving no trace of a fault code.
Could this be related to the egt sensor packing up slowly? Or should this not affect the running at all, meaning there could be another issue?
I have to go to work tomoz, and to be honest i'm not overly keen if she is not very well.

Thanks,
Mick
