1: wouldn't idle. when I got near home, if I let off of the go pedal, it would go dead.
2: ran great in the upper rpm range (3000 plus) but weak in the lower.
3: No check engine light.
It felt like it bucked and choked and wouldn't go.
I'm going to check the plugs, change the fuel filter, and go through the diagnostic procedures according the the Factory Service Manual.
I'm thinking throttle position sensor, fuel pump, or ecu. PLEASE, any help would be greatly appreciated.
Scott.

Sounds like you might have a bad mass air flow sensor, try unplugging the wire harness going to the sensor(located on the intake right before the throttle body), if the car will idle with it unplugged, then replace the maf.
