Hi,

The mileage on the car is about 30K miles. I seldom use the car and before this problem developed I have not use it for the last 3 months. The no.6 plug seem to be oily when the mechanic removed it. I have heard about the OVP in relation to starting problem. How do I locate the OVP? The mechanic is a Mercedes mechanic but I having my doubt as well. Just don't want to be spending for nothing.

Thank you on the response.

Regards,
