Guys, need some advise.
R20A1 in a CRV manual transmission. While doing a minor service, I took out the MAF sensor, sprayed it down with electrical parts cleaner, left it to dry. While in there, I used throttle body cleaner to clean butterfly (back and front), thing came out super black, I did not have the car running to spray the cleaner inside. Cleaned out the air box and hoses. Installed a new filter. Car starts fine and pulls smooth as ever (better then before actually).
Issue I’m having now, when rolling in neutral the revs are constant above 1500rpm. When I come to a stop, it returns to normal 850rpm.
I read online that the ecu needs to “relearn/adjust” to the now increased airflow after some time.
Is this true? Did I wake up sleeping dogs? While cleaning did I move the gunk to the idle control valve?
