If you have 35 lbs. fuel pressure with the line on, pull the line off and check it, it should rise to about 42- 43 lbs.(line off).You could check coilpack for proper ohms, should be in the 11-13 ohm range. Look for any signs of over heating on the ignition module, any gooey stuff, how old is module and coilpack, what condition are your sparkplug wires in?
Ohm out the coilpack towers front to back, should be between 11k to 13 ohms, this test usually catches most bad coilpacks.

Not without a Casper's tester.... aftermarket/Advance/Autozone/OReilly's modules are more often than not junk.... I'm nearly sure that is your problem. There are lots of sources for the oem AC Delco ignition module... that's the one you want...

Anyplace that sells acdelco parts....Cheapest I saw it looking around for you was $176.xx from gmpartsdirect (plus shipping)...
If I were you, I would see if I could find someone local with a TR to swap theirs out and see if that does the trick to make sure that is the problem. That is an expensive part to replace on a hunch.
If you can't find anyone near you to help, then, depending on your financial situation, I might keep trying the aftermarket modules until I got a good one... I've seen alot of people have to try 2 or 3 different ones until they got a good one.... and then use it while you save up for good oem unit for a spare when the aftermarket craps out.
OR
Pick up a used/known good one here on the board and go with that....
OR
another option is to swap the whole thing to a Type II ignition setup (different module, seperate coils).... not a very big deal at all and the parts are alot cheaper... do a site search, there's alot of info available here on the swap...
hope that helps
Also try GBodyParts.com Online they are easy to find.
Ok, so I found out it is not the ignition control module, coil pack, plugs, wires, fuel pump/filter. I still don't know what the problem is. I took it to a shop and they said the MAF sensor is good.
Could there be debris in the injectors? I did put some Lucas injector cleaner in - one or two tanks ago.
The mechanic said the car was "loading up."
The fuel pressure is still normal. I don't know what else it could be. Let me know what you think.

If maf sensor is known to "be good" I would check the fuel pressure regulator also. Check the injectors, disconnect one injector at a time, if the engine slows down, move to the next injector and do the same procedure. If when doing this and you find a cylinder where theres no change, then you have to narrow it down to see if it's spark related or a fueling issue, but since you did the ignition module, coilpack, etc. etc. and "maf is known good" continue here.
