never played with a maf-t before so not too sure.

but if you can lean out idle some, theoretically that "should" do it.

keep in mind that if your O2 is working and reading, leaning out the maf-t might not do you any good as your ECU will just tune it right back.

surest way is to take a look at your O2 readings, if it's even working. that should take most of the guess work out.
