"check engine soon" lite on, car coughs when accelerating, otherwise runs fine. Changed air mass sensor. Check engine lite went off. Car still hesitates when accelerating( problem did not go away)?

Short terminals A and B of diagnostic link. Turn ign. On, light will flash code 12 (flash. Pause. Flash, flash) three times, then error codes, then back to code 12.

If MAF is good then check fuel pressure.
