Ok, it is up to 120D temp, not close to operating, but...

It dies going into gear.
I plan to retighten the intake bolts and pull the TBI gasket to see what is up.

BTW, MAP is at 1.1V when it dies going into gear, if it matters.

Ok, I dug in today and pulled the TBI off to check the gasket, it was fine.  Then I started checking the base, flipped it over and the PCV port was blocked on the bottom.  AH HA!!
then I check the port and it was completely stopped up.

So, I cleaned the whole lower portion of the unit checked all the ports and put it back on.  So far so good, I drove it for 15 minutes without dying.  Now I plan to drive it regularly and see what else will show up.

I am hoping to get it running dependably to make it to the All Chevy/GMC Nats in Maggie Valley, NC.

Glad you found the problem. Hopefully that was it.

That Maggie Valley show is the same weekend as the Richmond Nextel Race....gonna work pit road again--look for me on TV.  I made it on TV during the Nat'l Anthem lined up w/ the teams on pit road before the race last September.

I went through the Maggie Valley a few years back while on a trip through the Great Smoky Mountains---beautiful place. Even saw a bear down there.

well after moving my focus and getting back to this, now it only dies in gear.  Yippie....  Haven't checked anything yet, just drove it to see if it was still gone...

Have you set the EST base timing yet? try pinching off the return line and see if it still dies...

Hi, I was referred to this site (by stovebolt.com) for this very same problem. Did you get it? And if what did it finally end up being? thanks.

No I haven't had time to trouble shoot it lately.  Base timing has been set BTW, but I haven't tested closing off the return line.

Timing was set, and clamping off the return as best I could on Saturday yeilded no different results.

I forget where we were at with this thing and don't have time to reread everything right this moment but pull the vacuum line off of the EGR valve and leave it off to eliminate that the valve isn't pulling slighlty open. Also what's your fuel integrator and block learn?

Sorry, little one has me scrambling for time.
Conditions as of today.
No codes
New IAC, EGR, TPS and basically the whole bottom of the TBI rebuilt
No vacuum leaks
TPS = .55V
IAC count = 25ish
MAP = 30's
Fuel pressure is 13lbs steady.
Base timing set
Clamping the return does nothing.

Once you crank it and it runs for say 3 minutes, drop it in gear (any gear) and it dies.

Did you unhook the EGR? What about Fuel integrator and block learn? It sounds like the EGR is openeing.

I didn't get to it last night.  I was just updating the post so you would remember where we were. 
Previously if I unhooked the IAC it will stay running, but that was a few posts back.  Haven't tried that recently.  Will check the rest tonight.

Unhooking the EGR didn't change any thing. (it was recently replaced in the beginning before this post was submitted.)

BLM is 134.
Not sure how Fuel Integrator is referenced on what I have...  I have attached screenshots of WinALDL..

Which trans do you have? Your TCC solenoid isn't sticking on is it? Try unplugging the TCC solenoid and drive it around for a bit and see if it keeps happening. You don't have the connectors criss crossed at the TBI do you? Also check with a timing light pointed at the bottom of your injectors and look at the spray pattern of your injectors. The strobe light will allow you to visually see the injector spray patter, just use an advance timing light so you can adjust the strobe. Hook it up to any wire.
