anybody no the specs on the tps sensor. i got as high as .49 and as low as .46 is that right, lost my haynes book

[Drick]

The recomended setting is 997-999 the best is 998 you may need to elongate the holes to allow for the extra movement to get to 998

[cobraetti]

anywhere between .94-.99, should work just fine. Or at least it did for me

[Stangzilla]

Yeah take a small rat tail file or a Dremel and elongate the holes so you can acheive .94-1.05 volts. Thats what works for me but I dont know the actual spec....

[JBIGBOOTSY]

Be sure to ground the voltage meter to the TPS ground and not the engine otherwise you'll get a diffrent reading

[stang fanatic]

+1 from jbigbootsy. you have to read between the signal and return wires to get the correct reading

yeh that how i read it, what does elongate mean??
and its a new bbk throttle body, should i put my old one on it and see how that works or if tht'll fix it, kus it never gave me a problem, but then again i never checked it, maybe i'll swap them and see how that works. because the car idle fine before i changed that.

[Stangzilla]

Well you know how the holes are round? Use a small round file to make them a little oval so you can move it a little more.. Do me a favor just look up what the word elongate means so you are clear on what it exactly means before you do it...

[stang fanatic]

ok...so the problem is that it doesnt idle well....how is it idling?

[JBIGBOOTSY]

I tried to elongate my penis with a dremmel tool and it diden't help, and it hurt really bad!

sometimes it'll work jus fine, but then if i cut it off then the idle will be erratic it'll keep jumping up and down from 600 rpm to 200 and then jump rite bace up and keep doin it until it cuts off.

when i start it for the 1st time of everyday it runs jus fine, but if i cut it off and start it back up then it idles like shit. i took off the new tps and looked at it and it looks just like the old one except its a lil bit bigger

Good dont look for the haynes book they suck get a chiltons

To test and adjust the TPS.

With ignition ON, engine OFF, and the TPS plugged in
1) You will need to pierce the wires with the test leads.
Measure voltage between sensor VREF (Orange wire) and SIG RTN (black wire). Voltage should be between 4.0-6.0V, if so, the correct power is getting to the sensor.
2) Measure voltage between sensor SIG RTN (black wire) and TP (green wire). Adjust the position of the TPS to achieve 0.90-0.99 volts with the throttle fully closed. After adjusting the postion of the TPS as required to get that voltage, move the throttle from closed to open and the voltage should move smoothly with the movement of the throttle plate to greater then 3.5 volts.

ok but how do i make the actual adjustment?

[stang fanatic]

by loosening the tps mounting screws and turning the tps. it does sound like a iac problem though.

yeh but i put the holley manifold on and a new throttle body on and now it does that it idled fine before and thats not gonna go bad within a day or to, but i also had the engine running when i tested it is that the wrong way.
