89 toyota pickup
My 89 toyota pickup runs great when cold, however, once it warms up it won't go above idle speed. It won't go faster than 30mph and won't rev. Just replaced mass air flow sensor.

Make sure your airtube is hooked up and sealed well. I had a bad leak and it would not let it rev up. I think what is going on is the leak is small enough to operate your Air Flow Meter to let the truck run but a big enough leak not to let it rev.
