2G Engine error codes P0100, P0105, P0110, P0505 and MAF?

[bnpimpn]

Alright I've got some error codes for my car.

- P0100 MASS/VOLUME AIRFLOW A CIRCUIT

- P0105 MAP SENSOR/BARO CIRCUIT

- P0110 INTAKE AIR TEMPSENSOR/CIRCUIT

- P0505 IDLE AIR CONTROL CIRCUIT.

after searching for the last few days( VFAQ, GOOGLE, this site), i think that most of the error codes have to do with my MAF, is this the right assumption? I have NO CEL lights on, How do i test to see if its faulty sensors?? If not in the MAF where do i find them? How do i fix the sensors or do i have to replace the entire MAF? Anyone with any suggestions for me please post them. I'm at a complete loss

I would just clear the codes for starters. You may have simply had the MAF and ISC unplugged with the key on at one point. It takes so many starts to erase old codes from memory. If those codes were active, the light would be on and you would have a poor running vehicle.

i did in fact start it without plugging it in, but my car does idle fairly rough on cold start...for a few min...could that be due to one of those sensors? If i were to clear them, and there actually was a problem, would the codes come back?

Yes, you already have them written down, clear them and see if they come back. Simply plugging in the connector won't clear the code from memory, this is why you have the codes. Like I said above, it takes a while for the computer to clear the code from memory when the condition that set the code is no longer there.
