Low fuel pressure
My 2000 corvette runs rough and really bogs at full throttle. A pressure check at the fuel rail shows 10-15 lbs. when running. Has anyone had a problem like this?.Is it the fuel pump or a blockage in a line? No codes are set.

1.) most likely you are in a non-Z06? Your throttle has a limiter set in it as a safety and will cut you off on fuel at about 200 rpm over redline. In the Z06 that limiter is about 600 over red line. THe safety feature will cut you when the throttle is all out... i hit that every so often when leaving in 1st or 2nd gear racing the engine. I hate that you feel the drop out and the response just tanks on you.
2.) fuel filter.
3.) is your fuel sending unit loud when ideling? You can hear it over your left shoulder. 1 on each side of the tanks. THey are known to fail. THey get noisy towards hte end of their lives... hope that helps.
