c1tice Posted January 27, 2023 Report Posted January 27, 2023 In my 1981 M20K the alt air will not stay closed. It works it way open about every 2 minutes. It is worse the higher and faster I go. Anyone have any suggestions that don’t involve duct tape? Quote

Schllc Posted January 28, 2023 Report Posted January 28, 2023 Is it actually open, or is it just the indicator saying it’s open? Quote
Pinecone Posted January 28, 2023 Report Posted January 28, 2023 IIRC, there is a magnetic latch to keep it fully closed. Check that. Quote

kortopates Posted January 28, 2023 Report Posted January 28, 2023 This often happens when the induction boot isn’t attached properly and the duct/boot causes an obstruction. Or the magnet is out of adjustment - but the later is rare.Sent from my iPhone using Tapatalk Quote
