Gen One - Thanks! I should have looked in the parts manual. What concerned me was that the bolts are different colors/materials - or seem to be... haven't checked them with a magnet. That issue is resolved..... somewhere along the way, the oil got hot enough to open the thermostatic valve in the adapter and oil is now flowing through the engine oil cooler. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Charlie - Many, many thanks to you for helping me through this. Much of it is terribly confusing in the way the instructions are written. Sometimes the instructions seem vague and other times they seem straightforward. What confounds me is following directions to the letter, only to find out later that doesn't apply anymore - or it doesn't work in some applications.

I did reset the distributor to the center so I have a reference mark and changed the trigger offset to 70.5 to match the timing light at 26* spark lead at 2000 rpms..... burned it to the ECU.

Now I need to figure out why it won't idle. I've tried completely plugging the brake booster line and it still runs at 2000 rpms...... so, I guess it's getting air through the IAC - pintle must be pulled back letting air bypass the throttle blade.

Should I retry the IAC - or try to block airflow inside the valve? Have you seen the GM stepper unit yet?

Try reducing REQD_FUEL?
