Hi,
My 98 S420 with 49K miles on it has some starting issues. Starts right up when cold. However after driving for upto 15-20 minutes, when I try to start it cranks for over 10-15 seconds and doesn't start. I turn off and start again it cranks for another 10-15 seconds and starts at the tail end. Any ideas or suggestions ??? Thanks
