nevr heard of 3 screws, usually just one as all it is is a variable resistor in a box. try turning one up with the engine running till it goes a lumpy idle then back a bit then do a test run.

hey sssstew,only gettin a chance to get back to this problem now,ive given up on tryin to make my "10pin converted to 8pin" box work,a guy who knows a lot more than me told me it duznt work-he chips and remaps tdis all day long and sez theyre def different inside,even though they look similar-but ill use ur advice on the proper 8-pin i got and see if i can set it up correctly,im half way there,thanx,chris.
