I know lots of you say 94-95s reset their own comptuers on the TPS so adjusting it wont matter. Well we adjusted on my buddies stang and it worked like a charm.

BUT

I have messed with my cars idle screw, tb bleeder screw too much and now im lost. I have a bad hanging idle which is caused by the TPS. The lowest I can get it is 1.03 and thats even with the holes drilled out as big as they can go.

NOW when my volt meter was hooked up I noitced when I adjusted the idle stop screw that it effected the TPS. Should I adjust this as far out/in so that my TPS reads .98ish then try to get my car to idle from there???

(its will idle way too low when I do this but then mabye I can mess with my throttle body screw to adjust the idle?). Anyone following me? Or is my TPS sensor faluty?

Anyone have any tips? I had it decent for a bit reset my comp etc but then It was a bit too low of idle so I touched the throttle stop screw and now its very bad again.
 
I've read almost all of those.

What I want a opinion on is

Should I adjust the trottle stop screw as far out/in so that my TPS reads .98ish then try to get my car to idle from there??? My tps is allready set as low as possible but isnt low enough yet.
 
i would rather have the idle stop screw adjusted properly and deal with the TPS after that, than use the idle screw to accomodate the TPS.

good luck.
 
are the SN TPS's and puter really that sensative? im a lot more savvy with foxes, and it really makes not a lick of difference on those (per datalogging).

i would be sure there are no vac leaks or other issues, and then start over, not unlike the steps in this article (which im sure you have read):
