ok i NEED to get this fixed or figure it out. the TB is on, and its great, improves throttle response a lot. now the problem is, sometimes it will hang at like 1200 rpms when i let off the gas. also, sometimes when it goes down to normal idle speed, it will surge up and down a little bit. i took the throttle motor off, and put it back on. i turned the spring counterclockwise, to the 2nd place where it could click in. any info?!?
