I know this topic has been beat to death, but I haven't really found a solution. I want my car to pull smoothly without hesitation (which is slight but noticable). WHat can I do to strengthen the pull upon acceleration? I've changed the plugs, had the injectors cleaned, air intake cleaned, fuel filter/oil filter ect. The car has always done this and it is starting to annoy me. Any tips would be appreciated.
