TB external return spring??
Anyone make an external return spring in addition to the factory setup for the TB return? I'm having an odd problem, after recently cleaning my TB and replacing the sensors, my throttle sits higher than normal while driving and if I rev the car the rpm's will drop back down to about 1500 and stay there. I have to get out and push the throttle maybe 1/16" to 1/8" back to the tab so the rpm's drop. With the car off I can manually turn the throttle open and it springs back to where it should. All my lines are oiled and do not bind. While driving if I let off the gas the rpm's will not drop under 1000 until I come to a stop and the trans downshifting forces the rpm's down. Any ideas?
