MIL Flashing
My MIL is flashing at all times, all gears, all speeds. The engine misfires very bad, I recently replaced the connector my MAF sensor, both check ok! The scanner reads EGR, EVAP, and AIR pump malfunctions. What should I do as far as testing these? Which is most likely the problem? Thanks

Re: MIL Flashing
It appears you've found the problem but...
A flashing MIL means a misfire(as you've realized)
Im not sure if GM OBD1 codes use the same pattern, but in OBD2:
100 codes mean a fuel related code
300 is a misfire code, 0 would be for unknown(a 301 would for cylinder 1, and so on)
and 4 is emissions related
