Air flow meter

Wolfie_:
Im guessing its screwed, but to confirm it, The rangie backfired today and then was reving the nuts and bolts loose. When I checked, the air flap had stuck open in the meter so released it and tried to start it but wouldnt start unless I wedged the flap open so the flap is not moving as it should. I guess its operated by electronics and something has blown/broken

What do you reckon?

hairyasswelder:
To be technical------ it broke.
It should be free to move very easily,
The airflow also controls the fuel pump on early 3.5's so that why not starting  ;)

jjsaul:
As mentioned in the first reply, it should be free to move.
Don't bother trying to fix it...i've broken a few in my time (LPG backfires) and they're quite fiddly.
Get on ebay, you should be able to pick one up for less than £20 secondhand.

Wolfie_:
well I put the new air flow meter on. and still no joy, when I try starting it was misfiring but wouldnt stay running. Thought id give the plugs a clean and thats when I noticed this



When it backfired it must have blew the pipe of as it had no jubilee clip securing it. refitted it and and started straight up  :doh:

Range Rover Blues:
I've had backfires bust my servo before now, it's worth having a pipe like that which will come loose when you need it to.  I ended up building a relief valve into my plenum to stop it damaging anything.
