    Default Any help? highly appreciated.

    My vectra Jul 2003 2198CC Petrol sedan is gone crazy. Firstly it went in limp mode a couple of months back and servicing found the Catalytic Converter is in pieces and glowing red hot. Replaced it with new CAT starts good but after a while went into limp mode again, servcing thought it might be the Head or the Gaskit but all fine then found the secondary oxy sensor is molten due to excess temperature in CAT replaced the oxy sensor. All runs good when start but after a while the Car went into the limp mode again and the CAT is still glowing, even the mechanic cannot find the issue with the car. He has done all tests and gone through all the readings, any help I'll highly apprecite.
    Thanks in advance.

    For some reason it seems like your car is burning too hot, this is usually due to it running very lean which can cause piston melt down.
