First off, have a bit of patience. (At least with me.) <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

Go ahead and get a DOHC throttle cable. They are different lengths, and they can affect drivability. That may not be your problem, however.
Just try that first and see what happens.

Man, a few months ago I was messing with my throttle body and I tried to take out as much slack as I could, but not make it too tight. Well, one of the bolts came loose just as I was pulling out of my house and coming to a stop sign at the end of my road, and the bolt caught the throttle body and kept my engine running at like 3500 rpms and I have an automatic. I about couldn't get it to stop and almost ran into a car. Next time I am making sure I don't over tighten the bolts.
