Three pages of very technical questions and answers, yet no mention of this highly important (to me, at least) part:

There is also a 10 to 15 second delay from a stop before the car will accelerate, regardless of how hard I hit the gas.

Do you mean that when you come to a stop and try to go again, the engine doesn't rev up at all, or you sit there at 5000rpm waiting for the car to start moving? HUGE difference in diagnostics, depending on your answer.

A thought/expansion on what Master Blaster is getting at......Have you pulled the exhaust off yet to inspect it or anything like that?

The problem is still persisting, but I'm taking that it stopped temporarily as a good sign. I was able to get a hold of a fuel pressure gauge. On the rail, it tested at 33 and went up in response to the throttle. There is no delay in shifting while passing. The transmission is still good, the car only sits there idling pily while I have the peddle pressed 3/4 of the way down. The exhaust is good, there is plenty of pressure coming out the back, but since the beast is 20 years old it wouldn't hurt to go ahead and replace the catalytic converter, and check it out while I'm at it. My toolbox decided to eat my 02 sensor removal socket, so I'll pick one up while at work today. I'm also going to go over all the basics again, check the plugs, the firing order, make sure wires are connected, all the fun stuff. Any chance there is a pdf or anything going over the differences between the 87 3.8 and the 88 3.8? I'm interested to see what all is different.

it has a throttle position sensor, right? could it be intermittently shorting out or something? i had a van that after it warmed up, it just fell flat on it's face and didn't throttle up.... no code even, replaced the tps and it worked like a charm

been there, done that, but isn't it intermittent? that would cause it to suck all the time
