trouble codes
my f150 1988 wasnt running right so i found the trouble codes.
Manifold Absolute Pressure/Barometric Pressure Higher Or Lower Than Expected
(when i unplug my map sensor it idles alot better, not sure if it is the sensor or a leak in the intake)
Throttle Position Circuit Higher Than Maximum Volt.
(not quite sure what to do about this. i bought and installed a new ecm 4 days ago after mine shorted out.)

there are other tests per manual to verify the wiring is good, but there is a good chance the codes are saying that the MAP sensor and TPS sensor are faulty. unplugging either with the vehicle running will set a code also.
