Hey guys, when I drive up to 65+ mph it starts to sputter when I keep my foot on the accelerator. It's even worse when the AC is on and when I have more weight(passengers) in the car. Help, its getting annoying.

Hello, how long since a Tune-up? Use a gage check fuel pressure. Are there any codes?

As far as checking fuel pressure, if there is no schrader valve, tee the gage into the supply line. On some vehicles it is easier for me to remove the fuel filter, tee in there. I haven't look at your fuel filter, it may not be practical. Just a thought.
