RE: what to do with an Airflow Meter
I assume those wires go to a device that screws into your exhaust pipe? If so, you have a 5-wire wide band oxygen sensor there. I have been told that an EFIE will work on these, but I don't have first hand knowledge of this. I have yet to talk to someone who has done this successfully.

You definitely have some options though. Read Tuning For Mileage.

I would do the handlings described for the MAF, IAT and CTS sensors. You'll go a long way with these.

If it's on the air filter it definitely isn't an oxygen sensor or any kind. Oxygen sensors are on the exhaust pipe only.

You only need an EFIE for oxygen sensors.

If I were you, I'd get some good documentation on your vehicle so you can identify what your sensor(s) are, and then you can go from there. If your car is fuel injected, then it'll have an oxygen sensor.
