C43 AMG Misfire
Hi can anyone help
I have a 1999 C43 I had the crankshaft pulley changed recently as it started makeing bad noises.
Since it has developed a misfire after 5miles or so once the engine is up to temp it will trart to miss on 3 and 5.
If you turn it off and on it rectifies the misfire.
You can encourage the misfire by more aggressive driving?
I have been told they have problems with sticking valves it sounds electrical to me??
Anybody help?
Jon

Hi. Either you have an air leak or a bad air mass sensor. ( HFM-sensor ) Or you valves for the secondary air injection ( If standard on this car? ) is leaking thus leaning out the mixture and therefore misfiring.
