It also could be the throttle cable is too short now that the Throttle body is higher. check cable length.

Those air aid TB spacers are thick. If you have a 700r4 auto trans you better adjust your TV cable too. Or you may be buying a new tranny soon

when i did it a couple weeks ago, i can verify the throttle cable issue... its borderline long enough with the spacer.. with just adding the spacers to the throttle bracket, the cable was barely long enough. even worse, the end tube part would hang up a little on the stationary part because it had gone past the point where it had a "guide". ended up having to tweak the bracket a little..

found my tv cable, although functioning fine, needs replacing from where it had apparently been laying on the exhaust at some point..

GOOD point about the TV cable. It's been awhile since I've done the TB spacer.

how do i adjust the TV cable? because i looked anyd both the throttle and the TV cable are at nasty looking angles....? i put a new gasket in and it runs fine now, i need to test drive it
but i wanna know how to make a bracket or something because i dont like how those cables look on the intake

my TBI spacer came with 2 spacer sleeves to go under the throttle bracket to raise it up... if you didn't get any, you could get 2 longer bolts and cut down some long spacers from various alternators.. they where about 1/2"...

to adjust the tv cable. depress the button and pull the cable all the way back into the housing. then give it full throttle with engine off. the cable should "click" out a few clicks..
