Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
Okay, more things to check would be plugs, wires, coils and CRANK sensor. That's for the ignition part of it.
Fuel injectors, fuel injector power covers the fuel part of it.
Vacuum leaks inside and out of the engine.
You would need a smoke machine to attach to the intake for internal leaks such as intake gaskets etc..
Check MODE 6 on the scan tool for more direct misfire information.
Check the freeze frame data for what criteria was met when the code set.
Your fuel pressure is also 4 PSI lower than specs call for, so the pump is bad and may fix this code .
Thanks again and please remember to rate me 5 stars and keep this link in case you need ma again later on.
