1993 Legacy SS won't rev

Post by superstock2 »

Car starts and runs okay, idle is a little low. Under WOT the car will rev and then hit a wall around 4-5k rpm. The car revs better when given partial throttle and under load in first gear the car barely runs at all. I replaced the maf (not OEM, Delphi) and am wondering where to look next. The gas tank was also pressurizing quickly. Any thoughts are appreciated.

Revs great until it doesn't sounds like a fuel issue.
