bought a new maf two weeks ago and the car has drived beautifully since but last night i noticed when i pulled up anywhere the revs started to drop and the car would nearly stall then pick back up bit worried as i spent £255 on the maf why would it do this, is it faulty ect.
ive got an induction kit but the old maf worked with that since i got the car any ideas would be appreciated

 

if you are running a standard ecu then try re-setting it

 

hi, i reset the ecu when i replaced the maf and knock sensor do you think it needs to be reset again?

 

If it iss a failed maff take it back and it will be replaced. Dont tell them you ave an after market filter, as this make it void.

 

thats exactly what im gona do but just wonderd if there was anything else what could cause this problem.

 

Idle air control solenoid?

Have you checked for error codes? - JollyGreenMonster.co.uk

 

il check it when she gets back with it

 

Ok. Mine was showing a fault with the idle air control solenoid when the MAF went, but after fitting a new MAF it seems to be fine. Strange...
