Alright, after replacing all seals in my engine last summer (including rings) and rebuilding the tranny, my car is acting up AGAIN. I have a 1990 integra, here's the symptoms, i'm guessing it's the Fuel Pressure Regulator:

Whenever i pull away from a stop and the engine is under load, it will stutter severely under 3000 rpms and will barely move. It feels like the clutch slipping then grabbing but i know it's not the clutch. Above 3000 rpms it's fine, but below that it will barely move at all. Also, it only happens when the car is in gear and moving, only when there is a load on the engine. It idles fine and if i have it in neutral and rev it it's just fine.

So what do you guys think? Fuel? If you guys could give me some input i'd really appreciate it.

Thanks,
-Timmy
