AHHHHHHh i've read so many damn posts about the idle adjustment screw on the TB and I have still yet to find it. I did find the end of a screw right above the throttle cable and i traced it back to the front drivers side of the TB. but there is just a little hole there. i tried hacking at the hole but no luck. What the hell am I doing wrong? Thanks

no pics but it is really easy to find... put you hand on the throttle of the engine as if to rev the engine by hand... you would turn the metel thing twards the from right? well when you let go the thing it rests on is the throttle screw/.. follow that a few inches and the head of the screw is righ=t there.. facing the front .

to get to the screw you have to face the driver twaord the from parrelell....

Thanks TransAmTBI. Well I found where you're talking about....and I saw the screw so I followed it to the front of the TB and there's just a little hole there in the (concrete) of the TB. I hacked away at this circle hole where the head should be and I got no where. Any ideas?!?! THanks

it is a plug to prevent people from adjusting it, just use an awl or center punch (a sharp one), poke a hole in the plug, then pry it out
