The problem. When driving or revving the car if you put your foot down and depress the throttle like a 1/4 the way and even less and keep your foot there the motor sounds like it's hunting and it bucks cuz it will get gas then it won't then it will get gas again then it won't. The thing is that after you depress the throttle or floor it it revves freely. The only thing is when you keep you foot at a certain point like while crusing it's hunts and revs up and down almost like a hunting idle but only when you have the gas pedal depressed and not moving it. But when you floor it revs fine pulls hard and sounds fine. Any ideas what this could be? thx in advance

Try hooking a fuel pressure gauge where you can see it and drive. Watch it as your cruising around the block. It sounds like a weak fuel pump to me.

Fuel pressure is good. Idle at 40 psi and raises with boost. Ill try that 02 censor trick. Maybe i should take my head out of may *** and see what the FC says about it. Any other ideas guys. Thx
