at a loss could it be the throttle position sensor and if it is do they sell the sensor separate?

no i do not hear a vacuum leak when under the hood looked for cracks and don't see any. No haven't changed fuel filter runs great when cold only bogs down when warm.

Check engine light is not on so do not have any codes to look up. Was on and said misfire p0300 p0301 and p0304 so think may be throttle position or coils.

My check engine light came on today as I was driving the car and the code was po776. which was something to do with the pressure solenoid B. No clue where this is or what it is.
