Finally got around to pulling codes. Some questions

[NY-Bronco]

So I finally got around to pulling codes. While the Bronco is driving, over the weekend something just did not feel right. I know its nothing major but something is off. It all happened after hooking up the AC unit. At first I forgot to put the PCV hose back in which I pulled out to make space to hook up the AC lines. After putting the PCV back on it got better but something is still off. By off I mean that at idle it sounds like it wants to die and while coasting downhill its doing the same thing. To combat that temporarily I just turned the screw at the throttle cable to keep the RPM higher. Someone mentioned that the exhaust smells a bit rich.

Its a 302 with an RJM harness and a A9M computer. The code reader is a Ford code reader by Innova:

Here are the codes:

KOEO:
81, 82, 85, 84

KOER:
12, 21, 94, 44, 33

The high RPM can be explained because I increased it. So the only non soft code is 21 (ECT sensor out of test range 0.3~3.7 volts) Can a faulty ECT cause this?

Anyone? Mr. Viper, where are you?;D

More likely, the engine wasn't at operating temp when you did the test.

Thats quite possible. I did not pay attention to that. Ill try again tomorrow.

KOER test 180 or better

if your battery was disconnected during the AC work, your ecc probably needs to be reset.

That is an INSANE amount of work you put into it man. I simply coul not get past the L section ;D My head is about to explode! But hell, at least I know what is what. Well sort of - I have a reference sheet now ;D Thanks dude!!

Yeah, it's not something you can skim over & grasp immediately. ;D But you can skim over it & pick out the stuff that interests you, and what applies to your setup, and then come back to it later.
