I have a 1994 Mustang GT 5.0 (auto) - I am just wondering... it seems that my car accelerates slower with the pedal all the way down than if I put the peddle about half way. Sometimes the car seems to slow. For example, I was following my friend to his house after school and we had pulled out of the school driveway and we sped off (I had the pedal floored), but I was just keeping up, not catching up to him and he was driving a 1998 GMC Safari Van. I'm just wondering if that is normal or if maybe I have a problem. Also if I give full throttle, I sometimes hear a loud rattling or tinning sound, I have brand new mufflers.
Any input would be helpful,
Thanks a lot!
