It's happened to me even before I got my new transmission. So when parking on a hill looking up. It's approximately a 12 degree Hill. When I get on the highway there isn't no throttle response not quickly as I'm used to in this car. But when I park down words the car is fine on the throttle response. Have any of you have this problem before? Im driving like 40 and then on the highway I push the pedal all the way down and it acts like it doesn't wasn't to go and goes a little bit faster but slowly. Instead of pushing throttle down and it takes off fast like I'm used to in this car Q50.

Have you noticed the fuel level in your tank? Does it do it all the time or when the tank is near empty? It could be the check valve in the fuel pump. Allows the fuel to drain back in the tank, but that also should make it difficult to start.

Also sounds like the ecu reflash problem. When you floor it nothing happens but then all of a sudden all of it happens?
