Yesterday i replaced my two 255 inline pumps for one Aeromotive A1000 inline pump. When i drove it home, it was totally fine and drove like it should. Then last night when I went out cruising, the car did what it has been doing for the past month. While at a cruising speed, giving it little gas, it has zero throttle response and when i go to put the clutch in...it dies. It restarts sometimes, luckily it did last night, and will continue to drive erratically, missing and backfiring. Anyone have any suggestions as to what may be causing this?
