m42 air mass flow meter problem?

[Hotjim]

Hey guys my 318is has been sitting a while and after getting her up and running she's surging when idling. When the air mass meter is disconnected it stops surging...runs like crap but it does stop.

Anyone have any experience with this issue, can it be repaired or is it just a replace job?

Cheers for any help

Remove the idle control valve first clean it out with carb cleaner, check for split hoses M42 has millions of the little buggers

That did it thank you very much John. It's a fascinating read Jos luckily my hoses and engine are in a hell of lot better condition that one! Know of anyone on here who has followed through with this?

Let me know if you need to replace any of those hoses, i've got a box full of them, split free obviously

[Hotjim]

Ha brilliant! Did you remove both the heating plates if so how did it run afterwards? Also where did you put the icv?

This is a sound thing to do when it comes to manifold painty time

[johnl320]

Icv is back in its normal place

Yes I got rid of both plates

Only noticed difference at idle tbh

Deffo job come manifold paint time
