This is a rather difficult problem to describe but I'll do my best. I have a 2003 Accord EX 4 cyl, sedan with 22k and some change in miles. When I initially bought the car, I was getting on average 29-31 MPG highway (which is what it's driven on 90% of the time). Lately, I have been getting in the neighborhood or 25-26 MPG highway, sometimes 27.

The symptoms are: (mostly by feel)

1. Must keep accelerator pressed with significant pressure to keep car at speed.

2. When backing off of accelerator, the car slows very very quickly (no coasting to speak of)

3. It drives, ALMOST, like the parking break is stuck or something. I can sense resistance in the forward movement (at least it SEEMS like resistance), but no brake lights are on and the parking break is not engaged.

I was told there was no "break in" period but I didn't push the car until I had about 900 miles on it.

Does anyone have any thoughts as to what might be causing the gas mileage to have dropped like it has?
