map sensor and IAC sensor causing my cold start to run like ***?
just wondering if the map sensor and IAC sensor would cause the cold start on my car to run bad for a few minutes if the sensors themselves are not working right anymore. by running bad i mean misfire/popping and erratic idle for a few minutes then it runs nice. thanks

we are having the same issue with a h22 and it seems to be a bad iac valve... check continuity across the pins on the iac and there should be no continuity.. if there is its bad.... check signal voltage on the white wire with a DVOM on the map sensor connector and it should be 5 volts... and the yellow and white wire should also be 5 volts..
