91 Brougham getting Diagnostic code 132
« on: May 22, 2013, 09:18:22 AM »
Hi, I have a 91 Brougham, it's been running terrible and stalling.  Yesterday I changed the plugs, distributor cap and rotor, but not the wires.  Now when starting the car the engine idles up and down and then when I put it into gear it's like it wants to stall, I have to flutter the gas pedal to keep it running.  And when I'm driving down the road it's like it wants to stall out and when I give it gas it sounds like it's bogging down and when I get to a light the car stalls. The service engine light went on and I am getting a diagnostic code 132.  When I look that up it says knock sensor, but the mechanic says that could be a false read out.  Also, I had replaced the my radio and receiver a few weeks ago with used OEM, because they both went a couple of months ago, I mention this because just yesterday the new radio started doing what the old one did when it was on it's way out, which seems like an odd coincidence that this would start to happen at the same time.  I wasn't able to switch the channels with the buttons and when I would go to turn the radio off it stays on until I turn the car off.

The mechanic is not available today, does anyone have any thoughts?

I Googled  OBD II Code 132 and got "O2 sensor, bank1 high voltage reading".

That can make the car run the way you are describing.

A 91 would be Obd1, so OBD2 codes wouldn't apply. I don't see a code 132 listed on the charts, I believe GM OBD1 were all 2 digit codes.  Could the code be E32, with some segments of the LED not lighting? If so, 32=EGR system error.

My error.

Here's the complete list of OBD I Codes:  http://www.gmtuners.com/OBD1_DTC.htm

EGR stuck open maybe?

Thanks for all the information. Good point Curly, definitely a possibility.  Thanks for the code list Brian.  My mechanic was able to squeeze me in, so I dropped the car off.  I'll post the results as soon as I find out.

You don't specify the 5.0 or 5.7 engine and I'm not sure it would make a difference.  I ran into a problem with my 5.0 '91.  Turned out to be a shorted temp sensor where coolant seeped into the sensor and corroded the wires.  As I recall, it shot an error code for something other than the temp sensor but that is what turned out to be bad.

Check the EGR valve, due to the age of the car it is likely the rubber vacuum diaphragm has gone south.

Well, mechanic still has the car.  The way the car was driving he was convinced that it was the fuel pump. He did get a code for the EGR valve, but when he tested the fuel pump it showed it was losing pressure.  I just called him he said he worked on the car and he is still not happy with the way it's running, he is going to test drive it again and call me back.  So maybe it is the EGR valve.

Mechanic called back again after his test drive.  Car was running okay with air conditioning off, but as soon as he turned it on, it was real bad.
