ok i took the throttle body off to change plug wires and now i have a problem. when i start the car it revs to wide open throttle. and then i have to shut the car off. checked everything twice to make sure everything was put back. any ideas? and one more thing is that now the RPM needle with the car off rests on the opposite side of the guage at like 9000RPM

 

Maybe you snagged the throttle or cruise control cable in the process? Maybe there is a huge vac leak now?

As for the tach... I dunno. I've never seen that happen.

 

sounds like the linkage is caught for the throttle. do the throttle plates come back to rest at ful close? check free travel of the cable.

as for the tach... idk problem with the cluster

 

there could also be a large air leak after the throttle body

 

ill check but as for the tach problem it just happened. never did it before. so it has to be associated with the problem i think?

 

you think if the TPS was bad it would effect the tacometer
