Just fitted new maf

[vrs.danny]

Right guys. Just fitted new maf to my vrs (Bosch) and now she is hunting revs when idling. Noticeable drop in performance. Have gone back to unplugged for now. Do I need to do an ecu reset after fitting? I know with my subarus I was needed, not sure about vrs though.

Cheers guys

Let it run for a bit, it may be the ecu sorting it's head out after getting drunk readings

You could try resetting the ECU by removing the battery terminals and touching them together.

I think that clears the learnt values.

Just done a reset. Left battery off for half hour. All sorted now. No more waning lights woo-hoo
