Hi
My 91 mustang has a sticking throttle body(the
accelerator becomes stuck in the closed/idle
position,especially in the morning or after being
parked for several hours). The TB is an edblk
70mm. The rest of the motor is basically stock,
except for eql headers and pulleys and ofcourse
an edblk intake.Is there a remedy or is this just
a fact of life?

Try tightening your idle screw a turn or so, and backing off your TPS a bit to offset it, then disconnecting the battery for a few seconds to reset the idle.
A 70mm TB is an overkill for stock heads and cam.

don't mean to "jack" your post, but i've the similar problem still.
sounds like how my car is in the morning and after sitting for a few hours.
my idle in the morning goes up, then down, up, then back down and dies sometimes before warming up.
i'm gonna change my O2 sensors to see if that's the problem then check the throttle.

Hey st5150,
I am gonna try exactly what you suggested.However,
when adjusting a tps don't I need a voltage tester
or something like that? And is this done while it
is running or just igintion on?

Yes, you'll need a volt meter:

Aim for about 0.85 to 0.90 volts.

besides trying to listen for vaccuum leaks, is there another way to check?
thanks in advance!

I noticed a lot of Edelbrock and BBK throttle bodies would stick, usually after warmed up though. Poor fit between housing and throttle blade. Accufab makes a much nicer throttle body.

Chances are your volt meter is out of calibration and not even .04 volts accurate so its not a big deal either way as long as the car idles well.
