Educate me on the air flow meter please.
Discussion
Well I'd been having a good summer driving the car around, but couple of weeks ago notice some oil on the garage floor again, so earlier this week dropped the car off again to have this fixed. Got the call today thatwas fixed (don't know the issue yet or how much), but he did say the car was running a bit rich and would need a new air flow meter soon.
So the question is, if I get hold of a new AFM, is this a straight swap? Just remove the old unit and pop the new unit in? Or are there adjustments that need to be done to the meter when fitting it? Considering I can get the part for half the price it costs the shop to get the part, I'd rather do this myself.

I've been through a few AFMs on my Griffith. They are a simple device which contains a wire that gets hot - and then cooled by the air flow which changes the resistance (I think !). Anyway, the hot wire is protected by gauze but can get contaminated and give a false reading.
There are cheap units available & some people refurb them so take care if buying a replacement unit.
The ECU can run with the AFM disconnected so if you get really wrough running, unplug the AFM to see if this is the failing component. In no expert but would think your AFM is working or not. I have a spare working AFM but won't be out to Japan until next year

Sorry I am only allowed to take the first answer where this is the easiest thing you can do on a TVR 
I will be ordering one from the UK direct from TVR Parts web site. This is less than 1/2 the price the garage quoted me for the part without fitting.
Got the car back today so happy again, even if it was another 600 quid down the drain. Leaky sump gasket, an oil change, a fuel hose and a couple of other minor items adds up fast. Picked the car up and there was a 4.0 MK3 Chimaera in the shop. First time to see 2 TVR's together for me over here.
