Error 32 w/ new EGR
Nate Sestrich
Had an error 32 on the computer, put in brand new EGR, but I still get
the error 32 (much less frequently though). It does still have a rather
rough idle as well. Air filter was a little dirty so I threw in a new one
too, just to be sure.
Can anyone tell me what else to look for, test or switch that might be
associated with the error 32? The Haynes and Chilton manuals are pretty
vague.
Thanks!

the EGR solenoid over on the other side, just above the water pump.

Cool, guess Ill throw on new one of those at it too. The EGR that was
on looked terrible inside anyhow, I had to bust off a bunch of carbon around
the ports. Needed it anyhow I guess. Ill take a look for that solenoid!
Thanks!

There's a thread over on Pennocks that has all you ever wanted to know
about the Fiero V6 EGR system, http://www.fiero.no go to the forums,
then hit search off the top right group of links, then search for
"code 32 buddycraigg warning" and you'll see it in the first page.
Trust me, you have to see this thread.
The Code 32 is set when the vacuum switch that's attached to the
solenoid doesn't see vacuum when the ECM thinks there should be in
the line that goes from the solenoid to the EGR valve. A broken
vacuum line, defective EGR valve, or switch can cause a code 32.

Thanks a bunch for the help. The article, admittedly, confused me a bit
more than I was to begin with, but Im an electronics tech for a living so
the whole multimeter testing thing sounds like a breeze. I was sort of let
down to read that this problem normally doesnt effect engine
performance...Ive been getting very rough idle as well as soot all over the
back of my car for a god month now. I was really hoping to clear it up.
Any chance Im barking up the wrong tree here?
Thanks,

up on the diaphragm inside the EGR valve hat. This will open
the EGR valve. The idle should deteriorate immediately and
badly. Release the diaphragm, the idle should improve within
a second or two. Next step, with the engine off disconnect
the vacuum line from the EGR valve. Use your finger to again
push the diaphragm up, then use a dampened finger to block
the nipple on the valve where the vacuum line was connected.
Release the diaphragm while blocking the nipple, it should
stay up as long as the port remains blocked. As soon as you
release the nipple the valve should close. If it won't hold
then the diaphragm is bad and the valve needs to be replaced.
Have you pulled any pther trouble codes yet? With the mixture that
rich you should have set at least an O2 trouble code by now,
generally a code in the 40's. If your O2 is bad it will run
rich, and the same if the CTS is bad.

Nope, no other error codes as of yet, and the EGR is brand new as of two
days ago. I will try what you said, not a problem. I was afraid that Im
burning oil, but my exhaust smells like gasoline. I havent had a single
other error code other than 32 for 2 months now and just got the fixing it
up about 5 days ago. Could it possibly be lingering carbon in the system
that is still giving me the error code? Or after replacing the EGR valve it
should clear right away? Im still hanging to the fact that my solenoid
might be bad, but Id hate to buy one if I dont have to. Ill give what you
said a try tomorrow.
Thanks,
Nate

Tsk tsk, Jazzman. Otherwise, we do trust you. :-)

Yeah, right. :)
You coming to the swap meet next weekend? I'm having a room
party at the hotel, all the beer you can drink if you're
staying at that hotel or have a designated driver. :)

I might make it but I found out this week that the transmission in my
Astro van is slipping and needs work. Might not get done in time. None
of the Fieros would make it, although I toyed with the idea of towing it
down to Ed's for a little servicing. Perhaps later in the summer. I do
have to be in Florida in May so I might make to the Swap Meet some way.
I do enjoy them. I'm a lousy drunk though -- I get mean for 15 minutes
and then fall asleep. It ain't pretty. I'm usually the designated driver
these days. :-)

The Annual (Maybe Last) Fiero Swap Meet and Get-together April 29th
weekend at the Fiero Factory in Huntsville, Alabama. I think it might be
the sixth or seventh. I only missed one, but it looks bad for this year
too. A great time. Not so much a car show as it is a time to shoot the
shit and sell or bring home parts.

Thanks!

is a small rubber hose going from the end of the solenoid up to a tube
on the firewall. Replace this, clear the codes, and see if they come
back after 5+ minutes above 55mph.

Actually it will, the ecm checks for the presence of vacuum when it
tries to turn on the egr and it checks for the lack of vacuum when it
tries to turn the egr off. This seems to be really common problem and
the #1 cause of the code.

As it turns out, I had a replacement EGR solenoid sitting in my
basement.... I totally forgot about it. Regardless, the error code went
away but the car still wants to stall out on startup unless I pump the gas a
bit. Any more ideas?
Thanks a bunch,

a cracked EGR tube or other problem that causes a vacuum
leak, a bad MAP sensor, TPS, IAC valve, etc. On startup
the car is in open loop, meaning that it ignores the O2
sensor readings and runs the fuel tables strictly off of
a pregrogrammed map stored in the ECM's "chip". Generally
it takes a minute or two for the O2 sensor to start
reading properly, at this point the ECM starts listening
to it and modifying the fuel delivery based on those
readings. So, if you've got a vacuum leak, that would
drive the mixture lean, which if small enough is no problem
for the ECM to compensate for after detecting the problem
from the O2 sensor readings. Since the readings are ignored
at startup, a lean problem would cause driveability issues
until the O2 sensor warmed up enough to start working.
That's just one scenario. Do you have a laptop or other
means to run a PC in your car? If so, you can build an
interface cable for less than $20 that will allow you
to use your PC to look at the data coming from the ECM
via the ALDL interface behind the cigarette lighter plate.
The software is called WinALDL and is free to download,
though the author would be appreciative of donations. Do
a google on WinALDL and the first hit should be his site,
including directions on building the interface cable.
