not sure what is going on but car hesitates at crusing speed which is about 45-60 mph and the CEL flashes i know check codes but hear this first... Only does it after the car is warm. I replaced the fuel pump, filter,spark plugs and wires still sputters i notice a difference and sputters less but still does it. I also noticed that when i redline i wait for it to back fire and i notice that the gas pedal is a lil easier to press like less pressure and it stops sputtering for a while and the CEL isn't on so its wierd just wanted to know what everybodys opinion is before i go do everything

Check codes.

Probably a TPS.
