Hello

My car seems to be "struggling" when I try and accelerate. It always does, but I notice this when I drive uphill also. It almost feels like the fuel is having trouble reaching the engine. I had a new fuel pump put in last month.

The check engine light is NOT on, and I recently put in a new air filter and fuel injector cleaner. I also had my catalytic converter replaced by the dealer in 2007.

Any advice?

Thank You
