[Shotimes] ECC Codes...

[Rich Edelman]

Replying to myself here, but my problem is solved...

It turns out the self tapping screw for the computer ground that goes through 
the strut tower was loose, and stripped. So the ground wire kept flapping 
around, the computer would cut, and the car would die. That's also why I 
wasn't getting any codes. The shop didn't find this at all, despite having 
the car for a day and a half and supposedly having many people look at it. At 
least they didn't even TRY to charge me a diagnosis fee.

So, I fixed the stripping by putting a real bolt and nut through the strut 
tower. Immediately I got back a bunch of codes:
636 - Trans Oil Temp Sensor Out Of Range
539 - AC or Defrost on
117 - ECT circuit grounded
118 - ECT circuit open
157 - MAF circuit below min voltage

Well, I stopped and got a new ECT and installed that. I had a spare MAF, so I 
put that one on.

I'm ignoring the 539 and the 636. I did accidentally have the heater on when I 
ran the test, and running the test again without the heater on didn't show 
that code. As for the 636, the car wasn't at operating temperature at all. In 
fact, it's 36 or so degrees outside. After I got the ECT (took all of 10 
minutes) and MAF on, the car started right up, ran fine. I let it idle for 
about 10 minutes to warm up, re-ran the KOEO test, and got 111, just what I 
wanted to see.

Thanks for everyone's help on this one, and have a great turkey day.
