I have a 1994 SSEi. The cars runs fine except when accelerate quickly.
The car will bog down then accelerate slowly. The boost shows only about 5.
Is the problem the fuel injectors, fuel pump or the super charger?
:?

I would guess fuel related, a clog or something is weak, like the pump. You should get a couple more pounds of boost, so it'* not the catalytic convertor, that would raise boost pressure. There is nothing the SC could do to lose boost. Does the boost gauge flutter? Quickly drop a couple pounds? Could be a bad boost control solenoid.

I'd bet bad BCS or a vacuum leak. Moving to 92-99 for the time being, maybe to Forced Induction when the troubleshooting dictates.

Please don't post mechanical problems in Performance and Brainstorming.
