I set my idle today from the link Andy put up awhile ago. The car idled decent with everything turned off like the instructions said and but stalled when I turned everything on. Anyone know why it did that? Number 3 on this site http://www.muscularmustangs.com/maintain.html

Then when I checked my TPS voltage I got .998 - 1.000 which is OK since its supposed to be .98-.99 but when I held it to WOT, it only read 4.70V instead of 5V... Do I need to get a new TPS or can I adjust my current one to read 5volts or is 4.7 good enough?

Iv'e had (4) diiferent TPSs on my car over the years, I have yet to see one hit 5.0 volts...I usually end up with 4.67, time and time again...

So you tryed that link....mine was fine thru the entire process...I expected it to die out with everything one...but it worked fine...

Do you know what your cam pulls for vacuum at idle??? just curious if this comes into play...mine was 15-18...i'm wondering how that TFS your running fairs out???

I'm not sure what the vacuum is at idle. I'll have to check that and post it up tomorrow
