Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi Mark, for a symp***** *****ke this I would suggest you replace the fuel filter. If you continue to have trouble I would have the fuel pressure tested. It sounds like either low fuel pressure or restricted fuel flow. The car should also be connected to a Mercedes tester to check for any fault codes stored in the engine control module. The fuel mixture may also be changing when the car warms up and causing poor performance.
