- I similar behaviour with my car. My Renault has a "Wide Open Throttle" switch
- (WOT). This basically advances the timing a little, richens the fuel
- mixture, and kills the EGR valve. The WOT activates depending on engine
- vaccuum, or when the pedal suddenly goes to the floor. Needless to say,
- at low speed, advancing the timing is not beneficial to the power as it
- is at high speed.
-
- I don't know if your car has one of these, but it might. It also might be
- momentarily flooding until the vaccuum picks up and sucks more fuel in.
-
- I'd live with it if I were you -- flooring your car drops your fuel economy
- to zero, and jacks the smog way up with all kinds of nasty nitrides coming
- out the back.
