the butterfly is close to closed, and i just need to tap the throttle to get it to close all the way, but other than that, it idles around 1500-2000 rpm (annoying) so im gonna try and get a higher tension spring, oh and hte reason its not opeing to wot is cause there is a small plastic peice hitting the intake manifold, i just need to cut it off, also, its opening to about 90%-95% throttle, pretty close to wot, but not quite
i wont know how lean or rich im running till i hook up my air/fuel ratio meter (odb1 wont run the blue wire mod on my apexi) but to compensate for the TB i get it to run richer now, and its made a bug difference, im now making power ALL the way to the rev limiter, where as before i stopped making power at 5900-6000 rpm
just need to play with it some more i guess
Sounds like you took it ups and didn't rebuild it right. And you plate isn't sitting flsuh in the closed position or you didn't add enough tension to the spring when reassembling it.
You can make the GT Mustang TB as tight as you want by adding a few turns to the throttle cam before you reinsert the butterfly plate.
As for adjusting the slack in the cable, you can space the end of the cable away from the pedal, inside the cabin by using zip ties as spacers. Or a more professional fix; cut of the lead stopper ont eh stock cable, at the TB, and use a brass adjustable cable stopper (available from the smaller non-Home Depot style hardware stores - usually in the same section as the lawnmowers or the "odds 'n' ends" aisle where you find nuts, bolts, sprinmg grommet etc. and all that sort of stuff in the plastic drawers). Remeber that the cable end on the Mustang TB is actually smaller than the Contour, so buy the right diameter stopper - take the TB into the store with you to make sure you have the right one. Once you have everything assembled and adjusted, cut off the excess throttle cable sticking through your new cable stop.
