Subject: FTE Small - Help Needed: '86 BII Failing PA Emission

This doesn't seem to have made it out to the list on my first attempt
yesterday (or I never received it back from the list), so I am
posting it again:

I am trying to get my '86 BII to pass PA state inspection. It is
failing emissions. How I can fail emissions and get excellent gas
mileage, I will never know...

I do not have the test results handy, so I can't say whether I'm high
on carbon monoxide, nitrous oxide (dioxide?), etc.

The first thing I did was run a computer diagnostic. I got the
following codes from the EEC-IV:

33: Insufficient EGR flow detected
42: EGO sensor voltage always above "rich"

Last year I replaced the EGR valve, but did not replace the EGR valve
sensor. Could a failure of that sensor cause the code 33? Also, could
that also cause the code 42?

I would like to have a reasonable idea that replacing the EGR valve
sensor will fix at least one of the problems above - spending $50 on
a part is an expensive way to diagnose the engine.

What else should I look at to solve the rich condition? I don't have
a shop manual and the Haynes and Chilton manuals deosn't seem to be
so helpful with this kind of diagnostic.

So far the airflow seems to be sufficient into the throttle body (ie
no birds nest or anything discovered) and the air filter is fresh.
The fuel pressure regulator (FPR) has also been replaced within the
last year.

The ignition timing was reset within the last six months (properly -
with SPOUT disconnected). I thought that was the culprit, but even
after fixing that I still have these problems.

All help would be appreciated.

Dave,
There are people on this list that are far more knowledgeable than myself,
with that said I have experienced the same issue. You might have a sticky
EGR valve or the exhaust pipe that feeds the EGR valve might be plugged up.
As far as the rich condition, maybe 02 sensor? That is just a guess.
Cleaning the EGR valve and the pipe going to it solved my problem.

Subject: FTE Small - Stalling 86 BroncoII 2.9L

After the engine has warmed up, not sure of the exact temperature/range
that it needs to be at, the engine will start pumping fuel into the
injectors, but not opening the air flow accordingly. This will happen
every single time when the engine is warm, but not if its cold. when its
cold, it does the increased throttle until warmed up, and everything is
okay. Then, when it reaches whatever temperature is needed, it tries to
stall in the same manner described. The computer has been replaced twice
now, and still the same problem. TPS has been replaced, and the air flow
valve on the side of the injector has been replaced too. everything checks
out alright, no check engine light, and no computer codes come up. If
anyone has some suggestions they would be appreciated. This problem has
been plaguing me for about 6 mths now, since i got the darn thing. I love
it, except for this one itsy little thing :)

Thanks in advance,

several items to check...
First, run the engine for a couple minutes then pull the vacuum line off
the fuel pressure regulator. If it is wet with fuel, the Fuel Pressure
regulator is bad. Next is the EGR valve... if it sticks open, it can also
cause these symptoms... After the truck is warm, the computer commands EGR
to turn on and the valve doesn't close all the way when you come to a
stop. That kills it.
Third is the Idle Speed control valve. My 97 Explorer had it's ISC
replaced already because it jammed closed and the engine wouldn't idle over
300 RPM most of the time, then all of a sudden would jump to 1500-1800 RPM
and come down to a normal idle... Replaced the ISC and it purrs like a kitten.

My Two Cents: I Find it easiest to get the snow out of my bed by simply
putting the tailgate down, backing up pretty fast and then hitting the
brakes. I derived this after deciding it was to troublesome to use the
snowthrower.

Could be injectors or thin oil. Ihave found in my 87 2.9l that too high or
too low fuel grades make it tick differently so I always use 87 grade now,
even if I have to go out of my way to get it. Mine also has one lifter that
ticks very loudly at startup when it's cold out (below 40 degrees) until the
oil gets flowing good.
