I'm guessing you mean p0103, p0200, ect... P0103 is for a MAF sensor, anything from wiring, sensor, or worst case PCM. Cant find anything for a P0200, but starting with P0201 are throttle body codes... P0300 would be your random misfire code. I have seen MAF sensors cause a random miss, exspecially if you have K&N oil on them.. And P0400 is an EGR code. Sorry can't give anymore detail then that, but hopefully it'll point you in the right direction.. Some aftermarket scan tools will only give you current codes, but if there's some in history, they wont show. Anyways, hope this gives you a start!
