I went to a shop the other day. And the guy told me that I could adjust my airmass meter because its an 005 from a 1987 900 s. I think he said you can take a ohm meter to the 3rd and 6th pins on the AMM and tune it to 380 ohms? there is an adjustment screw. I tried it last night and was not able to get it to change. Not its out of wack and starts bad in the morning. does anyone know about this?
