You would have to experiment with your one foot on the gas and the other on the brake, forget about the clutch then, but I think the Mirage's they are talking about is CVT models with 2 pedal. Dead pedal that's getting worse sounds like corrosion on your throttle body. Sounds like a throttle issue. good luck cheers
I have had this issue with work trucks never regular cars. My Nissan honks when it rains.
