Electric throttle body question

970 Views 3 Replies 4 Participants Last post by  dedmon27
Hey all,

I have a 2003 6litre 2500HD and I was doing some stuff and took the plastic intake piping off and noticed that the throttle butterfly isnt 100% shut (if you push it it will close more) and I was wondering if that was normal? I know from logs that when the car is at idle the TPS position averages from about 8-11%.

Thanks for your help.

for future reference if you have a electric TB do not force it to move in any direction. if you are cleaning it on the truck just turn the key on and have someone or something hold the gas pedal down and it will open for you.
