Idle after air filter change!?

[Skater gt]

Hi people,

Just fitted k&n panel filter to my 172 and it has changed the idle! It used to idle around the 800rpm mark but now it seems to stay just over 500rpm! Is it normal for this to happen? Cheers,

it shouldnt really change anything is it idleing steady or jumping up and down?

The idle will change if your old filter was clogged up quite badly.

It stays around the 500rpm mark, no jumping around or anything! a work colleague told me that the ecu might just need to learn the new airflow? I know bugger all about cars, this is the start of me learning! Lol

It's to do with pressure differences (normally in pascals) either side of the air filter. It's nothing to worry about buddy.

the idle would be higher if the OEM filter was clogged not lower with the new one on.

Ok no worries, keeping an eye on it for sure! Was worried bout the engine cutting out but so far so good!
