Look at GTRaptor's reply on adjusting the TPS voltage. ..?? I thought you were supposed to adjust it >>>>> http://www.allfordmustangs.com/forums/showthread.php?t=42678
Is this guy right??
- Thread starter rude_life
- Start date
Fox puters also adjust it upon start up, but surging still exists.
I would at least check the closed throttle value to ensure it is within reason. But specifically, I agree with Grady that you dont need to dial in a given value (0.97 volts, etc) per se.
Good luck.

A little more specific info on this topic.
Over time I've been sent d logs from several peeps to look at and their values have ranged from a low of about .94xx to a high of about .98xx volts.
Someone told me the other day he usually saw a closed value of 1.2 volts and he has never had any kind of prob, as far as he knows.
I took a quick look at some of my d logs and saw these values
1) 12-19-03 .9652 volts
2) 02-07-04 .9602 volts
3) 04-10-05 .9553 volts
1 & 2 were with the stock tb and no changes between the dates
3 was with a different tb
I have seen every now and then, the closed position voltage change or drift just ever so slightly.
for what it is worth, a little tps voltage data for your amusement
Like Mr. Hissin...I just don't think it matters a whole lot

Yeah no point in trying to adjust it. Even if you can fudge it to turn or whatever, the computer will probably just correct what you did. I thought I had a problem with mine untill I logged it, I'm not sure how, but the log read correclty from the computer even though the DiMM read differently. I wouldn't bother messing with it, chances are you won't fix anything.
Nice info Mr. Grady. With foxes, they are supposed to zero out if within tolerance (~+/- 20%) and if they cant, they toss a code.
I misread the initial post. I thought someone was installing a new TPS, not adjusting an existing one. When doing a new one, I would check it out. Otherwise, ahh, if ya want (I still do cuz I am nosey).
You and your logging - I am jealous!

YOU CAN ADJUST IT...IT HELPS...HELPED ME TONNES. You have to drill out the openings in the TPS where the bolts slide thru to make it more adjustable.
Im fricking confused now. My car runs like crap. If i ease on the throttle and stay at about 10% throttle it runs stronger and smoother but if i sink my foot into it, it just doesent do much. I dont know what the hell the problem is but its bull*****. In pursuit of a solution I have replaced both 02 sensors, engine coolant temp sensor, cleaned the MAF sensor a couple times, cleaned the air filter, changed spark plugs (gapped), new plug wires, new ACT sensor. I am so frustrated and i hate drivning my car sometimes because of it.
Like I hinted at in my first post, if someone is having issues, I see no harm in dialing in the TPS value. I would do it if I were in your situation, RL.
John, If you love logs, you will love my dog.

rude i doubt its the TPS check it anyways and let us know what its reading.
its the grey/white wire, use the pos on your volt meter, put neg to ground.
