First of all thank you for replying so fast.
I didn't have much time this past week to do anything.
I did some of the tests and it gave me a 2231 code and something about a sensor G28 came out ot a friends computer.
So I guess that should be my starting point ...
Any suggestions ?
Should I perform any other tests ?
Thanks again
