I have a 1988 Mazda 929 with a V6 3.0L Fl engine. It is an automatic and has 222,996 original miles. I bought the car early this year after owning the same kind just before that. This one had a new engine put in it and it runs very good. But it gets a lot less gas mileage than the one I had previously; About 19.5 MPG at its best verses my old one that got up to 26 MPG. It seems to run a little loud and vibrates some of the things in my interior. The check engine light also comes on when I am accelerating, then as soon as I let off the gas it goes off. It does this every time! Might it be my Mass Air Flow Sensor or something related to my fuel system? Please help! I will be more than happy to donate and spread your good name if your answer fixes my problem!
