i have a 2003 clk 500, it was throwing codes for the camshaft position sensor, it was giving me trouble starting would have to try tow times here nad there, i replace the sensor and now it seems liek ever time i try to start it takes two to three times of crank it over to get started any ideas,, thank you

 

when was the lasttime you changed your sparkplugs/oil?....maybe take a few out and check the clearance gap...make sure they're within specs.
