Yes, I still have the original spider and fuel regulator. Unfortunately I was unable to work on it last weekend. I hope the car will continue to run for a bit before I can make it back down to Louisiana.

Next I get a chance a pressure gauge is next on the list. From the last time I was in it, I fear the pressure is low. Won't find out till I get started though.

 

Long time since I updated, the car is still going and fuel economy is way up with the new pump! Have been working with the rough idle problem and found a thread with the exact problem I was having. As with his, it only occurs at hot idle, when it first starts, it idles great. Also same as his, idles right above 500 RPM as it gets warm, and as the RPM takes it's little dives so does the oil pressure. Turning off the AC reduces the severity of the symptoms.

However I did have a code for the EGR, I pulled it, cleaned it and put a new gasket on it. You can see on the old gasket where there was some blowby.

Cleaned the MAS, TB, and IAC valve.Here is a picture of the IAC to illustrate how dirty it and the TB was.


The is check engine light is gone but the problem remains. It makes quite a click whenever the RPM dives I took a video but you can't hear it.
I was informed that once you check the code you have to drive ~50 miles for the computer to rescan, maybe it will come back then.

I have not put a pressure gauge on my fuel yet, because as I was about to purchase it I got into a discussion about my situation. After some tinkering and checking the code with a couple of guys, I ended up going the route I went. I plan on changing the EGR and IAC whenever I get some extra scratch. The car runs fantastic as long as it is not idling. I was wondering if anyone else has encountered this situation other than the above post, which ended without resolution. Also am I doing the engine undue harm, or can it go a little longer till I can get the EGR and IAC?
