I have a 99 Cobra and recently had some problems with the intake. I checked the TPS voltage and got a 1.7. The car is now running fine and I no longer have any reason to think anything is wrong, I have been told it should be .97-.99. Is that right? Have I got a problem?

if i remember right it should be BETWEEN .95 - 1.0
i have a 98 and mine did this as soon as i changed my throttle body. as far as i know the throttle position sensor is not adjustable and if it goes out of spec it has to be replaced
Alright, thanks. Also, the car is running fine, what kind of symptoms did you notice, or should I notice due to this?

well what happened with mine was RIGHT after i changed my throttle body I pulled it out of the driveway and took it around the block… when I would accelerate either hard or not and take let off the gas and take it out of gear to shift the rpms would stick/hang for a while… I would have to put it into gear to get them to come back down. This went on for a while until I talked to some guy at ford who said I needed a new tps. For a while I thought it was a vacuum leak though but it wasnt
Ok, I replaced the TPS and still got a 1.7. Any other ideas? Could it be the throttle body?

wait you have a 99? hmmm... i think yours may be adjustable actually lol... ok are there 2 holes in the tps for mounting to the throttle body? actually.. if you want to i will just pm you and give you my number and you can give me a call and i'll explain to you what to do...
That is a different engine, throttle body, and TPS than mine. My TPS is not adjustable like the earlier models. So I dont know what else is wrong with it. I have recently removed the intake and throttle body together, but the throttle body has never been removed from the intake. ??????

yeah i didnt think it was adjustable... but i am reading things saying that it is. do you have the 2 mounting screws? and you said you have never removed the tb from the intake or removed the tps sensor from the tb? weird man... i dont know what to tell you. it shouldnt be acting up unless there is something wrong with it. and you bought another one and it didnt fix the prob
I wonder if there is something wrong with the throttle body itself, read this and youll know how it all started... http://www.allfordmustangs.com/forum...ad.php?t=80108 I fixed the intake and the car is running pretty much fine, but I keep getting check engine lights p1130, p1131, p1132, and the TPS voltage is too high. I changed the IAC and PCV valves to get it back runnuing good and thought the TPS was probably bad too, but I was wrong. Now I dont know what it is.

i can check those codes for you if you dont know what they are. did you already get the codes read to find out what is causing the computer so throw them? i will get the codes for you
One of them said something about running lean, another one said something about the fuel trim, and I cant remember the other one. So I dont know what to think???
