Presently showing P0305(cylinder #5 misfire) which is cyl 5?
History - 3 weeks ago, car dies and won't restart, no codes. Conferred with Marty at Just Answers; he said it was crankshaft position sensor, changed it and he was right. Car runs fine.
1 week ago, right front headlight burns out, change it and remove air cleaner hood and attachment to MAF sensor in process; next day car runs rough, stalls when giving it gas at low engine speed. Code is P0150 or 110(I forgot which but MAF) Put in a EBAY $99 special, stalling when giving gas at low speed disappears, MAF code gone but idle hunts and stalls. Drive it for 50 miles, hunting disappears(computer is learning?) but occaisional stalling at idle but improving. Any thoughts. Car has 140k, original plugs, wires, etc. (I know plugs need changing.) I sure miss the simplicity of the older cars.

 

It was the MAF sensor, put in an OEM Bosch MAF Sensor that I got from ALL MERCEDES in Oakland for $185. Moral of the story, use only OEM parts.
