i know this is probable a stupid question but but i pulled codes the other day on my 93 f150 codes came up voltage high low to tps and something else dont remember my question is i cleared codes did no work but truck seams to run better now is it possible clearing codes made it run better?

 

It happens.

 

What was it doing prior to all this ?? Idle problem/stalling ??

 

the idle would not stay steady up and down and as i would drive from time to time it acted as if it was loading up would have to push the clutch in and rev it up then would be fine for awhile but now that i have cleared fault codes it runs great and i didnt do anything to it

 

You have 2 sensors on your throttle body...Throttle Positioning sensor TPS and a Idle control sensor...sometimes cleaning them will help.
