OK. All back together now. Seems to be working fine. I have been driving for almost 5 days now, maybe a total of about 200 miles, and probably about 15 drive cycles and no more MIL. I have filled up the gas tank once since fixing, and it filled nicely without any restriction (but that never was a problem). Once again, it seems that cleaning the gunk out (and this time replacing the contaminated fuel tank air filter) fixed it.
There is something new that is a little bothersome. Now, occasionally, it is a tiny bit hard to start on the first try. Every once in a while, it will act like fuel is not immediately getting to the cylinders and it will take 2-3 seconds of cranking to get it to start up. And then even more infrequently it may stall out after starting, as if it were starved for fuel. But always a second attempt to start and it starts right up with a 1/2 second of cranking, just like it always used to do.
So far, it has never failed to start, and more often than not, it still fires right up on the first try. But that 25-30% of the time that it seems to falter a bit at first leaves me wondering, what has changed or what could I have done to create this. It is possible that a new and completely coincidental problem has occurred.
P.S. I did find a wiring diagram in a factory service manual that I didn't know I had - the switch side of CCV goes to pin 79 of the ECM.
P.P.S. I forgot to mention, that it makes no difference whether the engine is hot, worm or cold, seems very random. Also, I did disconnect the battery for about 20 minutes to fix a battery terminal right after putting it all back together - maybe it is still in "learn" mode ???
