CLK 430
Will not stay running
2000 clk 430 125K miles
I have the classic symptoms of a bad crank positioner sensor. The engine will die when idling. I replaced the cps 1 1/2 months ago (AutohausAz) and the car ran great for about a month, but just in the last 2 weeks it's doing the same thing. I replaced the fuel filter yesterday and the plugs were replaced 25k ago. It doesn't idle rough, but if you listen carefully whenever the a/c is on and the compressor cycles on the rpms will drop ever so slightly then recover, thats usually when the engine will cut off.
I was looking at replacing the cps again, but before I do, does anybody have any other suggestions? Thanks

I had the same symptoms...changed CPS..same problems later. It turmed out to be a bad fuel pump. Have someone check the fuel line pressure. Pump is an easy install if it needs one.
