Hello Preacher!
well, no check engine light?
It would be a good idea to have the car hooked up to a Proper scan tool or diagnostic unit to see which sensors are reading what.
The mass airflow sensor would be a good thing to look at in this case. I'm sure its removeable for inspection, perhaps you could clean it as well... but its not as common a problem on your car as say, and Echo.
The car runs fine above idle? Not like it has a misfire, as they won't idle nice on 2 or 3 cylinders....
This would be a place to start in having it hooked up. who knows what the computer is actually seeing... maybe the computer isn't seeing a camshaft signal apparently...
