ZC running bad

my zc is running like shit, its rumbling and misfiring real bad and I'm getting a code 3,5,14,15...please help

code 3 and 5 are MAP related

14 is electronic air control and 15 is ignition output signal...

you have all the wiring hooked up right? what ecu are you using and is it a new one to you?

gonna double check the wiring first of all then I'm gonna check the vacum lines and if it all checks out good, gonna make a trip to the wreckers and buy the map and iac sensors, I know I should buy them new but don't got the green, I need something to make my car run better, I'm using a pm6 ecu, its new to me and it the one of the 3 I've tried to work so I'm gonna stick with that

would the fact that my map and iac sensors were for a dpfi setup and not a mpfi setup be the reason why they don't work?

No.

I reseted my ecu and the map codes went away, so I took it for a drive and now the codes came back, so I reset the ecu again and its gone again, whats goin on??

it just doens't detect the problem right away drive it around and it'll prolly come back on... so have you checked the wiring and vaccum lines
