1989 90Q sluggish performance

I've been trying to fix this problem for over a year now... When I try and
accellerate it feels like something is holding my car back and will
stutter/surge (the brakes have been checked/replaced). The problem seems to
get better after warmed up a bit. Here is all I've done to try and fix it:
replaced all fluids
replaced fuel filter and pump
new plugs/wires
new distributor rotor/cap
new ignition coil
new timing and other belts
new O2 sensor
new catalytic convertor and muffler
Anyone have any suggestions on where else I should look to fix the problem?

Well, it sounds like you have replaced all the parts that didn't cause
the problem.
Is this a N/A I5?
The first thing I would look for is a vacuum leak, probably in the
intake boot but could be anywhere in the vacuum system or multiple places.
Check for a leak in the decel valve. This is located in the passenger
fender behind the fuel distributor in the44s.
Try a can of Teckron injector cleaner. Do you have a problem with poor
starting?
Let us know what you find.

yeah, it's a N/A I5 and I forgot to say that I also replaced the intake boot
to
. I'll try and track all the vacuum lines and see if there is maybe a
crack in one of 'em and I'll look for that decel valve also. Thanks! I
hope this works.
