Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
Did you clean the throttle chamber while you had the plenum off?
Yes.. Any time you replace or clean the throttle chamber you need to do a Idle relearn.
I can provided you with the steps to manually do this. If this does not work, or if you can't get it to take it will need to be done with a scanner.
If it still has a problem running, then you could have vacuum leak.
Hang on while I get you the steps.
Those are the steps to perform a manual idle relearn.
Give that a try and let me know how you make out.
