2004 E320 issue
What about the basics? Engine air filter? Spark plugs? Fuel filter replaced? This may have been done if you had a recall for leaking fuel pump. How many miles on the car?
Lastly, what about the gas pedal itself? It may not be working properly now? Are you able to rev the engine when the car is in park or neutral?
airflow sensor and the throttle body , any tips?
Once you've gone over all the basic maintenance stuff, if you still have an issue, I would suggest finding a local Mercedes mechanic. The basic maintenance you have to do regardless. Might as well save money doing it yourself. But if it doesn't solve your throttle problem, then instead of throwing money at it, find a trustworthy mechanic familiar with Mercedes. Might save you time and money that way.
