Well... took my standard air filter off the other day to work on the fuses. Since I've put it back on the car has been idling at 2000RPM, (normally just under 1000) which is a pain because it makes loads of noise, it drops back down after 5 seconds (ish) but it never did anything like that before.
I've had the air filter off again because I thought it might not have been sitting flat and letting air in.... but.... it's still doing it
Hmm... any ideas? I'm going to get a smaller K&N this weekend so I hope this might help?
Thanks! Ryan
