Ok so at idle my ltfts are at 16.4 which means vac leak.....got some carb spray and sprayed every possible leak area......no change in idle.....wtf i recently put in aluminum lim gaskets with the l32 lim and genv and im running a silicone gasket on sc and tb adapter plate......im stumped.....i guess it could be on the bottom of the tb since i couldnt get alot of spray up there....
