RE: 2000 s40 Engine revs and accelerating
I would firstly check the throtle wire for any broken branches and after that I would check the throtle sensor for any dirty contacts or similar electrical mulfunction. I know the solution sounds simple for such a serious problem but I guess it is better to start from the simple staff. Good luck

Did you replace your spark plugs recently? I had the same accelerating problem. Reading through these forums, and reading the topic 'spark plugs' everyone recommended copper core spark plugs. i was sold Champion Double Platinum plugs at the store originally and then when i switched to NGK copper core plugs the problem went away.
