ok. the code is p0510. closed throttle possitioning switch? is that what that is? and i changed the plugs and wires and that didnt help at all.

Ok, I know the dtc definitions book reads "closed throttle position switch" for a P0510 code but, The haynes manual specifically for the Aspire reads "idle switch fault" which makes me think maybe this has to do with that adjustable, one wire on/off switch, located just under the throttle cable on the throttle body.
The reason I say that is, the tps codes for a single tps equiped car like ours are the codes P0120-P0124
The purpose of that switch is to supply a ground to the ecu at "closed throttle only" once you're anywhere "off idle or higher" that switch then removes the ground signal.
It can be checked with one of those trouble lights with the point on the end.
You'd just attach the clamp end to the battery positive, put the point end on the switch's connector and then when the throttle's closed it should light the light, when you open the throttle the light should go out.
If the computer thinks it's closed all the time it may simply be stuck shut or just shorted out (possibly from corrosion). You may actually be able to get it working again and not have to replace it. Do not spray it with brake cleaner!

The precision is the religion for me!
