No if you install it with the plunger extended it will work fine.
Did you also clean out the throttle body?
This vehicle ran fine though until the a/c work was done?
Is it only bad at idle and run good other wise?
ok i have a scan tool how do i relearn the idle?
It is the scan tool at the dealer. I'm not sure if it can be done with the other scan tools or not.....
Have you tried to drive the vehicle to see if it would improve?
