I have had this same issue with my 88GL Coupe since I've owned it. Runs great and gets great mileage but has a bog while accelerating. If I were to accelerate from a dead stop without feathering the throttle the car will bog down. Have not looked into the PCV valve yet and I do have a new fuel filter on the shelf.
It has never really bothered me too much but it would be nice to be able to enter traffic without having to worry about being rear ended due to slow acceleration.

Just went through all this. New ignition everything made things better. A new throttle body from a car at the junkyard fixed it more.
I had a check engine, so replaced both EGR solenoids with 33 ohm resistors and ran a vacuum line bypassing each of the two solenoids. The car as of yesterday runs perfectly now. The check engine light never came back.
If you do have the solenoid valve code, then I'll help you out on this with info and pics. Those cost like 90 bucks each, and the junkyard just had crappy ones to swap out with my crappy ones.

Try running a wire from - side of battery to bottom bolt on coil bracket and cleanup body this bracket must be well grounded or weak spark and injector pulse

what everyone else said. tune your spoob up. get some gas additive and run it through your car. find someone with a timing light. replace your fuel filter. replace your PCV for 3 dollars. drive it like the gutless old beast it is.

Loose intake manifold bolts, or bad intake manifold gaskets or cylinder head gaskets that need to be replaced, will cause a bog that will drive you nuts, and will also be accompanied by coolant disappearing from the overflow bottle and a white residue on spark plugs.

A bad O2 sensor or one that looks like it is hooked up but actually is not, will cause an incredible amount of bogging.
