Pat,

Welcome to 16V hell! Just kidding. But as these cars get more miles on them, they become more labor intensive. Seems they all get idle issues at some time.

To check the air flow meter, you need to check the #1 and #2 connector plug with the key on and the plug connected. Should read around 0.8-1.0 v at an idle opening of the air flow plate and increase smoothly to approximately 5.0v at WOT. No open circuits or spikes, nice linear voltage while you manually depress the flow meter.

Good luck and let us know what you find.
