'95 C220, 205,000 miles.
About a month ago I went to pass another car on the highway, and the engine bogged down and began shaking. When I let up on the throttle, the engine returned to normal. When I would accelerate beyond 2/3 throttle, the shaling and bucking would return. When I turned off the engine and started again, the problem disappeared until I needed to press the throttle more than 2/3.
Having gone through many posts here, my guess is that I need a fuel pump relay. I know I need a wiring harness, but so far the only symptom definitely related to that condition is a CE light which cannot be extinguished.
I also have an SRS light which come on after start and stays on for a minute. From other posts, it appears this is seat belt resistance. If it were the slip rings, it would come on and stay on, correct?
Thanks.
