PO300: Random/Multiple cylinder misfire detected
PO301 Cylinder 1 misfire detected.
PO303 Cylinder 2 misfire detected.
PO303 Cylinder 3 misfire detected.
PO304 Cylinder 4 misfire detected.
PO411 Secondary air injection system incorrect flow detected.
PO507 Idle air control system rpm higher then expected.
My friend advise me to change the idle air control module (throttle body) or the mass air censor.

 

Sounds like you need new coil packs (it's a recall if you haven't got it done) and a new MAF sensor.

 

Might want to look at going with the bolt down coils from the 2000(ATW) they are hitachi/beru coils.
