no i meant base timing..... make sure the crank and cam are @ 0* sometimes a skipped tooth is enough to throw off all sorts of stuff..... as far as the codes, im not sure how the old stuff worked, have you verified the lines for any breaks? a friend of mine had a maf problem, and went through 3 mafs, finally a toyota specialist found that somehow some of the maf wires got kinked and threw codes....
