So my best guess now is that my pressure regulator is not functioning right, or that there is some sort of clog in the fuel system, possibly in the return line. I'm thinking since I'm not a mechanical expert and have limited tools, I should probably take it to a shop and have them try to fix it.
Since my pressure is going up when it's supposed to be dropping, I'm thinking I may be running at a rich condition. Either way, my accelration is absolutely terrible. I did say it was smooth, but that may be somewhat relative -- I can tell that something just isn't right. It really does feel like it's just not getting enough gas or air.
Thanks for your other suggestions though. I need all the help I can get. I really want to get her running right again. Anyway, I'll keep you posted on what it turns out to be.

After the fuel pressure test i would deff. run a compression test just to rule out any mechanical failure such as bad rings(doubt it) or valve not closing properly. If everything turns out ok then no internal worries and you can focus on something else.99 Trans Am M6

OK i finally got my car back from the body shop and was able to fix my driveability issues by removing the mass air flow sensor and taking the end housing off.I was then able to clean the little wires which were really dirty simply by wiping them down with dry q-tips .This changed how the car drove alot.It now pulls much harder and no more stumbling or hesitating.This I think will fix your problem,have you tried to clean it yet?Anyway I put new plugs and wires after I cleaned the MAF.The back 3 on the passengers side were a mother----er.It took me like 3 or 3 1/2 hours.I did it all from above without removing coil packs.Anyway hope this will help you.
