ECC Stumble?
 

This was the oddest thing. Started up the car, temp gauge flush with 100* [not cold cold, but cold]. Turn heat on shortly after, and before the ECC can register, I put it in reverse and gave gas. Not for anything would the car go anywhere.. it just kinda stumbled, then the ECC clicked and blower turned on and the car ran fine. I have cold start stumbles, with good plugs, wires, o2, but this has never happened.

I'm thinking bad ground somewhere perhaps? I have good voltages, and I had the stereo on, and it was playing fine... not like the alt was going crazy charging or something.

Also in case it matters I still have the QDM issue and my fans don't come on, and i got the car stuck in a ditch last night real bad... only had trouble getting it out, not starting it or anything. Also had it in the heated shop at school and defrosted it before the above problem. Luckily no damage... but i sure did get it stuck good!

wierd
 

Sounds electrical to me. Start with the Battery cables, ground wires, fuse continuity, and breakers.

Already checked out batt cables and grounds... all are fine [at least engine grounds]. I tried reproducing it again, and couldn't do it. I guess I have to wait for it to start doing it again....

It did it again! Exact same situation... after it did that, stopped the car, put it in park and tried again after heat kicked on and it didn't do it. It has something to do with the ECC on, but not on long enough to fire up the blower.. and that delay between it causes no movement just stumbles.
