Hi guys.

So I've noticed my MY99 wagon is acting a little strange.

The engine revs drop down to about 100rpm as I'm slowing down and down-shifting (stopping at a red light, etc). This doesn't happen every time I slow down but it happens more often than not. After it drops to around 100-300rpm it goes back up to around 900-1000rpm.

When the car is on boost, it kind of hesitates and then comes on slightly, then hesitates again then comes on full boost. It's weird.

The car smells very strongly of petrol even after a short drive.

I noticed the rev drop and petrol smell quite a while ago...shortly after my car was serviced my RMS. I only just noticed the hesitation just recently though.

I've come to the conclusion that it is probably my AFM. I just need a confirmation that this is the correct diagnosis. I've been driving off boost since Wednesday just in case.

I have no idea what panel filter is in my car. I have an APS cold air intake.

Any help would be appreciated.
