92 stumbles during acceleration

Changed fuel filter, checked fuel pressure at fuel rail (45 with key on and 40 with engine running) no engine light. What else could it be? How can I find out?

Re: 92 stumbles during acceleration

When was the last time the Plugs and wires replaced? And what kind of plugs are in the car?

Also does this car have the Magnavox Ignition Control Module( Plug wire terminals on opposing sides...

Or does it have the Delco Type II( Plug wire terminals on the same side )

Also make sure to check the Vacuum lines running to the top of the throttle body, I have seen these fail time and time again on the Tuned Port 3800 and even a slight leak can cause driveability issues
