    Have you checked your TPS throttle postion sensor? I had a similar issue and come to find out (after replacing many other items) the TPS was faultly. There are tests for it in the Bentley, Haynes, Chilton manuals. If you pulled apart the intake and unplugged the TPS and plugged it back in you may have pushed it over the edge or simply introduced crude into the connector. Pretty simple to check and they do go bad.

          I'll check this now, although my idle problem is fixed...no more air leaks. Would this issue cause the odd acceleration? That is something I will check regardless.

          haha yeah mine is in there good and tight I double checked it and triple checked it and then did a few times after that just to be sure. Its good and set in, thankfully I do not have an air leak anymore so whatever the cause of my current problem is is due to something different. Good suggestion though.
