Slow acceleration - Pls Help

Hi all,

My father has a C200K 163hp, 2003. It has 52,000km. Months ago I drive it and feel it has a slow acceleration than before when it is new. I had changed air filter, fuel filter and clean the fuel tank: it improves a little but not as my expectation.

Why should I do then ?

Did you change the engine oil? Mine made a difference when I switch to Mobil 1 0w-40 synthetic. Which is recommended by MB.

That might or might not fix the issue. I doubt his problem lies with his exhaust system -- although it might probably not.

Have you tried an ECU reset?
I'm assuming your father drives quite slowly. The ecu will adapt to that and shift sooner and what not.

I think instructions on how to reset the ECU are on the forum.

Do you think your MAF might be going bad?

Read that afterwards.

Thank for your comment. We currently are using Shell Helix Ultra 5W-40 full synthetic in our Benzs
