If your serious, i found the paper with my chicken scratches on it.
My hand writing looks like my doctors...
I'll happily take a picture of it and post, but only if your actually serious.

IIRC, someone mentioned hard metal heater hose T lines available somewhere?

Also the first time in a few years that my press has done anything other than flatten things to perfection.
Nice to have it earn it's keep.
When i bought it, cranking that handle for what felt like an hour to get it in a position i wanted.
I said f this and bought the 20 ton pneumatic hydraulic jack and adapted it.
I have flattened beer cans to perfection, pennies (making my own washers), etc.

There are some from Gruven for $80 each (about $175 shipped) and some from JTR/Stealth Conversions for $70 shipped for a pair. I have the Stealth Conversions Ts. Pics, etc. in my build thread here.

Throttle learn done, fixed the issue.
From the FSM,
With Scan Tool - Reset Procedure
Ignition ON, engine OFF, with a scan tool, perform the Idle Learn Reset in Module Setup.
Start the engine, monitor the TB Idle Airflow Compensation parameter. The TB Idle Airflow Compensation value should equal 0 percent and the engine should be idling at a normal idle speed.
Clear the DTCs and return to the diagnostic that referred you here.
Without Scan Tool - Learn Procedure
Important: Do NOT perform this procedure if DTCs are set. Refer to Diagnostic Trouble Code (DTC) List - Vehicle.
Start and idle the engine in PARK for 3 minutes.
With a scan tool, monitor desired and actual RPM.
The ECM will start to learn the new idle cells and Desired RPM should start to decrease.
Ignition OFF for 60 seconds.
Start and idle the engine in PARK for 3 minutes.
After the 3 minute run time the engine should be idling normal.
Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.
⇒ If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles.
After the drive cycle, the engine should be idling normally.
⇒ If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6.
Once the engine speed has returned to normal, clear DTCs and return to the diagnostic that referred you here.

I like the "with the scan tool procedure" best, took like 5 seconds.
