In a previous post, I pointed out that I am using a different AFM with
my new 2.1 and I attribute that AFM to providing excellent gas mileage
without O2 sensor input.

There is a plug in your AFM that can be drilled, a screw put into the
hole, and by pulling up on the screw, the plug will come out.  There is
a screw under that plug that can be adjusted for proper mixture but you
would want to have the proper sniffer equipment hooked up so that any
adjustment wouldn't make things worse.  I've never messed with that
screw ... but I know it's there.
