Thanks So i should check or have shop check all hoses and also change plugs or spark plug regulator. So youre saying no coil packs thank you for your advice and help
i doubt its coil packs because it seems to favor one side of the engine
Thanks would that be the drivers side or passenger i will have a friend pull up vacuum system on alldata. Thanks any hints on work to look for?
I'm not sure with that vehicle. Im a good problem solver though. I know car repair and you should do fine with those tips.
Thanks i didn't find a spark plug regulator when i searched intwrnwt is that the same as a voltage regulator
No. I did some looking and that car may not have one. It has a turbo?
yes its twin turbo
Voltage regulator sits on top of the engine center. IF that goes out, you will have misfires on both sides of the engine. Your problem is most likely the ignition coil pack assy also called a cassette that needs to be replaced. Approx 1400 plus labor. IS your engine tuned for performance?
No its stock. Benz just told me $1200 for coil pack i see standard ignition on rockauto for $800. So from the codes do i need left or right side coil pack
