thanks for the response. I think what you're saying is bang on. This problem did infact start shortly after I did my spark plugs. Inorder to do the plugs, I had to remove the componets you're talking about. Also I did take a cloth and softly attempt to clean it....after that this problem began.

Please describe the following "throttle return springs are in place and not broken,there is a coil spring on the front of the throttle valve which breaks and drops down, not obvious unless you know it's there."

How can I check for this, and diagnose the problem?and also how can i correct the problem? Thanks
