Po300. What is my ideal reading supposed to be for my MAF sensor? I am just wondering. Currently it is at 0.012 area while driving.
Changed cap, rotor, plugs, wires, distributor. Cannot seem to find a vacuum leak. Never did compression test.
Motor runs fine once in awhile. When at speed and a slight incline shed start acting up.

On average, at an idle you should see between .5 and .8. Wide open throttle should be between 4 and 5 volts. The reading you mentioned seems very low if you get it when driving.
