1999 clk430 150,000 well maintained. A few mornings ago when I tried to start my car it started then turned off two different times before it finally stayed on. it did that again later that afternoon when I left class. Then, that evening I was driving and out of nowhere it just felt like the engine switched to a lower gear. I pulled over and put it in park, then took off again. But she wouldn’t go above 25 or so. I’m not mechanically inclined, so its hard for me to describe this. Does anybody have an idea of what might be wrong? Approx $$?

Just got a 99 Merc. C-280 it came with no manual, changed the spark plugs, to give it a tune up, it is still sluggish, got it checked, coil pack #2 bad, if I am looking down at the engine where would coil pack #2 be located, also could it be possible that if the codes were not properly cleared out, can the computer cause the same problem, and or if  the CEU is bad can it effect one or more coil packs, or would a DIO identify that the computer is bad.

Thanks to all who can help with this….
