1- let him check the pins inside that ckp sensor connector for any backed out pins making a poor intermittent connection.

2- Was it scanned with A Mercedes Star scanner & all modules scanned ?

3- was an OEM sensor or advance auto ,auto zone aftermarket part

4- when the car don't start at that moment did he check for fuel & spark & confirmed what is he missing,we needs these 2 things to stay running

Expert:  Chad Farhat replied 9 months ago.

yes please do

I m online daily from 10 am till late

1-also the fault code numbers & also ask him to unplug the mass air flow sensor while the car running does the engine stumbles when he does

it will set a check engine light and code for mass air flow sensor , but he can plug sensor back in and clear the code and it will go away if nothing wrong with it

Just reply back when ready and we will continue

A 5 Star Rating is much Appreciated
