As first post go, this is not a good one, First of all, look at the section you have posted it in. Secondly, what vehicle do you have? As crystal balls are in short supply around here, it may take a while for someone to be able to A. Guess what vehicle you have, B. Guess what symptoms you may be having apart from poor acceleration, and C. pick the correct diagnosis from the several dozen possible problem that can cause poor acceleration. In the meantime you could always try posting your query in the correct section with a little more info about your problem.
