So I've had my 2000 C230 Kompressor for a few years now. About a year ago I noticed an issue where it loses power a bit when accelerating heavily. I drive 100 miles every day to get to work and back on the freeway, going 70mph. I have no problem reaching or maintaining that acceleration. However, if I ever need to accelerate heavily, the car starts "surging" where it looses power and comes back and loses it and comes back. The moment I go back to a more reasonable acceleration, it's fine.
I really only notice this when I try to pass someone. However, this morning at a stop light, I had problems accelerating for a few moments. And now I'm worried.
In the last year, I have replaced the spark plugs and wires/boot things. I've also replaced the alternator and the mass airflow sensor. The mass airflow sensor has actually been replaced 3 times now in the past few years, but the first two times were my fault. (I added some engine cleaner to the oil, but since the oil was leaking into other sections, the cleaner got on the MAF and killed it.)
I've searched the forums, and I see several other posts about the same thing, but they are rather generic, being "my car looses power a bit what do I do?". I'm wondering if the fact that it ONLY happens when I stomp on the gas could help narrow it down to something a bit more specific that I can try to rectify. I'm thinking fuel pump or filter, but that's because those are the only two parts that I'm aware of that sounds likely. I'm not a super mechanic, so my diagnostic skills are not the best.
