Can we discuss the TPS?

[1badsuv]

Well, I just had a strange TPS issue arrise-it would have been discovered sooner if I had measured voltage, instead of using my SCT livelink fo r the first time. All I saw on the graph was a moving TPS signal-I didn't know the display well enough to know it was over 1 v too high--ha ha


I had washed my engine bay, and since that incident my transmission quit shifting.
Low and behold it was counting 512 at idle-about 2.1 volts.

I'm needing a replacement

A bit of background-
I have a heavily modded Mercury Mountaineer with a 94-95 Mustang style intake manifold, EGR neck and throttle body on a 347 cu in engine.

So, I come here for discussion-
I notice there are 2 styles available for a 95 mustang GT --and they seem to reference 2 common 4 digit prefix numbers-

F1SF
F2SF

The motorcraft replacement numbers are

DY 987
DY 976

Now-can someone tell me if there is a preferred TPS to use?
I'm now beginning my remote tuning thru
www.hensonperformance.com

But for this question I am looking for experienced answers. I know you guys have them

Or, maybe I'm making too much of a small issue-but this little sucker has a lot to do with EEC-V tuning-load-and shift cycles--

It seems its only a new type of part , usually they will discontinue old products when the manufacturer does not support them anymore and it seems it could be this issue according to RockAuto.com DY987 is discontinued so maybe they are the same but different manufacturers.

Now-let me ask-
Could one be for manual transmission and the other for auto?

Orielly has both versions-

ec 3021=F1SF
ec 3049=F2SF

these are borg warner part numbers

Probably but i dont see any diff between the operation on both TPS however to dismiss the doubt i will look on my stock TPS on my manual car. somebody could chime in here with their original TPS on a auto?, i will post the number latter

Thanks
Everywhere look for this part-they ask me the first 4 number prefix.I
Even the ford dealership couldn't give me a straight "I know this for a fact" answer.

Bump for the night crew-
any ideas?

Maybe Wayne can share his experiences.

I've had to match them up before but I went with aesthetics, not numbers (since the puters are always wrong it seems).


Good luck.

Oh boy--

See, I don't have an original one to look at--ha ha
