I just put in a tb that I bought that was bored, now my jeep is idling super high iv replaced all the sensors and vacuum lines and no luck. could it be the tb??? please help me guys.

thanks,
Alex

 

how high is super high?
What is the TB bored to?
did you get the Throttle Position Sensor installed on the TB correctly?

 

try disconnecting the batt for like 10 min...then reconnecting it. i havent installed a aftermarket tb on my jeep so i do not know for sure if this is common. but typically on my previous cars, after installing something new while the computer is adjusting the revs tend to "hang." so let it idle for a while and if it doesnt come down at all and your sure everything is all connected, im assuming the aftermarket tb has a idle air screw that can be adjusted?

 

Idle air is controlled by computer via TPS, no adjust screw
Touch battery terminals together for ten seconds to "clear" PCM
I didn't get a High Idle issue when i installed my bored TB, but could be caused by an increase in airflow....

 

Idle is controlled by the iac ( idle air control) its in the throttle body and its different from the tps, could also be a vacuem leak

 

Whoops, typo, my bad
I meant IAC

 

yea, mine did that when the IAC needed to be replaced. It idled around 1200-1300 rpm's. Replaced the Idle Air Control Valve and now it purrrrrs.

 

ah alright. clearly you can tell i havent inspected under the hood since i got the truck, aside from a oil change. she runs and gets over anything i throw in front of her and thats all that matters for now
