I suspect I have a faulty air flow meter, can anybody tell me what readings I should be getting? At the moment the readings are
Engine off 2.09 grams/second
Idle 3.88 grams/ second
2k revs 7.85 grams/secon
3k revs 11.72 grams/second

The reason behind me checking is that I had it booked for a remap and it was way to lean to continue. I've checked for air leaks and it seams to be air tight so my thinking is the airflow meter is causing it to run lean

It's a 2001 bugeye by the way
Cheers

 

Sorry, I can't help with the readings. I've heard they can go go slowly and give iffy readings but I've never had it personally - they've always just stopped reading completely for me.

Surely the mapper should pinpoint the cause of the lean running pretty quickly?

Swapping it out for a known good one (again the mapper surely has one!?) would quickly tell you of its causing problems.
