you're welcome and thanks for keeping an open mind about all this. Yeah, the vac lines get old and with split ends. Toyota sells longer bulk lines which are metric of course, but local auto shops have them too. I just like the looks of oem vac hoses with Japanese writing and lines on them for some reason. I think we have two different metric ID sizes of vac lines under the hood.

Did Matt sell you the fuel pressure adapter thing outside of his website? I still don't' see it for sale on his site yet. Thx for the link on the IAC. Is this the one?

Yep, that's the one I got.

And I just contacted Matt via the email he has listed on his account here. He told me he has the adapters available, just not listed on his website yet. I think it was $70 or so. I left mine attached in case I need to check it again. Any issue you see with me leaving it attached?

The only other thing that I could think of (beyond what you've done) is the throttle position sensor (TPS). But, let's hope that you're good to go now. Happy to see that you're rolling again.

@Old Nick do you know if there is a good step by step guide for replacing the TPS on this forum? I think my stalling issue is fixed but it still bogs down a bit when I go to take off. As you say, the TPS is basically the last thing I haven't replaced at this point.
 
Here are a couple threads on the replacement and adjustment procedures.

Thread 'Throttle position sensor'

So I pulled the codes on my CEL and it came back as a bad throttle position sensor. I ordered the part and picked it up this morning. Is this a simple install? Does the throttle body need to come apart? Thanks for any help. I sold it yesterday and the light came on right after the sale ended. I want to make it right prior to shipping.

Thread 'TPS Set-up'

I have a '92 with 215,000 on the clock. For the last few months it has been acting like it is running lean in certain throttle positions; that is starting from a stop, applying some normal amount of throttle it stumbles alot and back-fires through the intake (pop-pop-pop). It is worse when the engine is cold.

After extensive research on this forum I changed the fuel filters, checked the plugs and wires and finally setlled on the TPS. I tested it according to the Chilton manual, which it failed. I bought a new one from Toyota, installed it to no avail. It runs the same or worse. I...

I find it easiest to use the search engine of your choice and just put in this generic statement: IH8MUD 80 series - then you put in what you are searching for (e.g., TPS sensor replacement).

Also, if you haven't already download the FSM and EWD from the resources sections.

Thanks, man. That's the old "Here, let me google that for you..." trick. I can't believe I didn't think of that myself. I'm still a forum newbie. Thanks for the links!
 
Update: So I "had" an issue with the motor getting bogged down sometimes when I was taking off from a stop. However, the second and third time it happened I just mashed the gas pedal and it took right off. Now it hasn't happened in several days so I think I may be in the clear. Maybe the vehicle "learned"?

A funny/good thing happened after all of these fixes as of late: I went on a 4 hour trip yesterday and got 15.2 mpg. I don't think I've gotten better than 12-13 in previous year of driving. Might some of these fixes helped the mpg?
