Question about my Accord LX - it's a 2003 LX model with the 4 cylinder engine. When i start it up in the am, the idle starts at 1500 rpm, then as the engine warms up, it drops down to around 750 rpm. This concerns me a bit since i can put the car in drive and it'll go up to about 15 mph without touching the gas pedal.

Is this normal or what's up? the car has 52,000 miles on it.

Thanks,
Brian
