I read a ton of posts about adjusting the TPS. I did it today - and it was clearly one of the best/easiest things I've done on my 2001 5.4.

I found it at 96.4 volts. Adjusted it to 99.4 volts (as close as I could get to the recommended 99.8).

I wasn't having any specific issues - as in rough idle, high idle or stalling. I chose to try it based on the general benefits claimed. The improvement to throttle response was worth the 20 minutes spent.

Search 'How to check & set your TPS' for a comprehensive thread, with detailed directions for this worthwhile adjustment.

 

I was interested in this, but I didnt have a multimeter, now I was just bestowed one, I think I may give it a try again, after getting my tunes and CAI, my throttle response was increased tenfold, how much do you think it may affect it now?

 

do you mean mili volts? because it is impossible to get close to 100 volts when the tps only gets a 5v. plus the battery is only 12v's.

 

Yes mili volts
