Missing at cruising and light throttle?

[SpeednV6]

I'm trying to figure out why I'm getting a miss at light throttle. If I cruise
at, let's say 30mph at a constant light throttle, I'll get a miss. All numbers
on Scanmaster are within range. Every sensor is new including coil pack and
module. Vacuum lines, checkvalves, and solenoids are new too. My static fp is line off at 50 psi, anything under and blm's go to 140-150. Gas milage is the pitt's as well. The Maf is stock and has both screens.

Pop the vacuum hose off the EGR valve and try it. If better we'll go from there.

I will try that tonight and post results.

Thanks.

Static FP is 50psi?
It should be set at 42-43 with the line off. Sounds like you have bad fuel injectors. Also, what type of chip are you running? What type of fuel pump do you have and is it hotwired?
