Hi,
Did you get this resolved? My same model car just started doing this (sluggish), chocking feeling while stepping on the gas. Even when parked. This is out of the blue, no recent maintenance to blame on. I did a tune up (plugs, cable, rotor) about a year ago. Just haven't figured out how to replace the fuel filter. I pulled out the fuel pressure regulator though. Still debating if its bad. Any ideas? Thanks.
