Code results
88b2 automatic 2.9L been sitting for two years.
I've done the OBD tests a couple of times and here's what I get:
KOER
12 - Idling issues - I'm clueless about this one
21 - ECT - I'll pull it this evening and replace it
77 -Operator error - what can I say, I'll try again. I'm stepping on the brake then turning the wheel at the right time. I am confused about if or when to goose the engine.
KOEO
86 & 89 both relate to the tranny solenoid? I'll trace wiring before dropping the pan. Any suggestions would be greatly appreciated.

First of all was the engine warmed up when you pulled codes? Shortly after the engine ID is flashed the scanner will give a single flash, thats when you goose the throttle-and you wont get the 77- and then it will flash your codes.
Have you got the instruction manual that came with the code scanner?
What sort of problem are you having?

Slight correction: After engine id is output, you press the brake just like you're doing (not necessary on BII's to turn the steering wheel, as we don't have power steering pressure switches.) Then, engine speed will increase and the computer runs through the KOER test. Right as the engine speed returns to idle and just before the codes are output, you will get a pulse/flash -- the goose pulse. It's a narrow window, but now is the time to goose the throttle.
87XLT is correct in that many times ECT codes will be set if the engine isn't at operating temperature. Also remember that codes by themselves cannot diagnose a bad sensor. You could just as easily have a broken wire.
KOER 12: It seems this is more of a symptomatic code rather than diagnostic. Anything that makes the engine run rough can trigger this code. Make sure the IAC valve is clean, but otherwise more diagnostic work needs to be done.

I just bought the b2 a couple of weeks ago. It runs rough although I haven't driven it 10 miles yet. It warms up then loses power and starts missing. When I got it the air filter and plugs were filthy and I've mostly been addressing the immediate needs. I'd like to make it my daily driver.
As far as the ODB goes, I ran the bronco at 2000 rpm for 2 minutes to get it to normal operating temp per what I read on the internet. Today I printed off the 32 page guiide and will study it this evening.
thanks

Drove around the neighborhood this evening to warm the engine. Noticed more houses for sale since last time I made the circuit.
Anyway, I got the engine warm and got 12 & 13 codes and the 89 & 86 mentioned before.
Engine ran fine until got to normal temp then started trying to stall and only ran well when accelerating.
Noticed the "ticking" when I was parking the beastie.

Sounds like classic O-2 symptoms, runs fine cold, bogs when hot & clears up at full throttle.
But you did'nt get a O-2 code.
It will be interesting to see what the other guys think about that 86 "adaptive rich limit reached in fuel control program"

Well i did some checking & I see that 86 is only an Adaptive rich code on the 1.9 liter engines.
So as you said it looks like a trans solenoid code.
Looks like as soon as it goes into closed loop it's screwing up.
But the codes that are coming up dont seem to be any help.
It will be interesting to see what this turns out to be.

Well I hear a hissing when my engine is running.. Anybody know where the 2nd hose goes from the PCV valve? I have one big one that goes to the TB, then there's another elbow above that, which has been taped off for a lower idle.
There's also another open vacuum line on the drivers side of the engine right next to where it says 2.9L. There's 3 or 4 lines coming off of it, and there is supposed to be a vacuum hose on the bottom of this multi-outlet/inlet.. but I don't know where it goes either. Any ideas?

On the front of the engine theres a vac hose between the EGR tube & EGR sensor.

It appears that you have a case where the EEC-IV computer isn't able to detect the fault (other than noting that the engine is running rough through the 12/13 codes).
What's the fuel pressure/fuel delivery look like? Any gas in the vacuum line to the FPR (after running the engine)? No spark leak? Good compression on all cylinders?

Well I cleaned the air bypass and the throttle body last night. Today I left work early and warmed up the engine and got a code #41 (R): System lean - Fuel control instead of the 12 & 13 I got last night. So I'm off to the parts store for a fuel pressure gauge. Stay tuned.
Interestingly when I toured the neighborhood today I noticed a performance decline much sooner and the beastie struggled even while accelerating, which I didn't notice the previous trip referenced above. That makes me think this may not be 02 related.
