Whats going on with my car!!!
So I own this CLK 55, couple weeks ago the whole car stared to shake and the idle is a bit irregular so since I used to own a CLK 320 I know the routine for a shaking engine
I went trough this procedure
1. Cleaned the MAF sensor
2. Cleaned both air filters and the airbox
3. Went to the garage got my engine mounts checked both OK
4. Looked for vaccum leaks with break cleaner ... none
next thing I did was to remove a park plug it seemed pretty finished
my question is can sparkplugs cause the whole shaking and little idle fluctuation WITHOUT sending a checkengine for misfire?????
thanks!!!:
Hope this helps.
Paul
