ok I've posted here before about my w202 c200 hesitating when accelerating not all time but sometimes, its worse when cold, this morning i was in second going along and it felt like it was stalling but then a massive surge of power to bring it back to normal happened after a second or two, I've ruled out MAF and coils and fuel filter they've all been replaced and no joy, I'm wondering now if its fuel pump or injectors? the fuel filter was not changed previously for years and was very choked up changing this made a huge difference but problem remains any ideas welcome, If all else fails I'm ready to bite the bullet and send it into my local mechanic to get sorted, that and the bizarre intermittent extremely high pitched whine/squeal from front at 30-40kmh then disappears completely above this speed is also doing my nut in!!
