Hesitation in 1994 Cadillac Fleetwood

I changed 1 oxygen sensor ...made no difference. I will change the second.

One trouble code (00-32) said, "EGR open command did not change fuel mixture during off idle operation."

Where is EGR located so I can change it?

Thanks,

Ray

Symptoms of a bad map sensor on 93 cadillac fleetwood brougham


Well code 23 is a faulty signal from the manifold air temp sensor. The sensor is telling the computer the air temp in the intake is out of range compared to the other readings.
Code 26 is a quad driver problem inside the computer.
Code 34 is a MAP sensor signal saying the vacuum is high when it should be low compared to the other sensors.
They may be connected or separate issues. You could check the MAP with a vac gauge.
I would clear the codes and see which ones come back again.

Car will start for a few seconds and cut off then wont start at all also has code p0174 and putters bad when i try to give it gas


this trouble code means your system is running to lean on bank 2, Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1. You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration

1994 saturn sl 2 oxygen sensor light came on replaced it. now the code is saying the upstream oxygen sensor input volage above normal operating range???? and theres a bad odor coming from car???


It could be the oxygen sensors but when you said there is a bad odor I would bet that you have a bad EGR valve. It will send a code for the oxygen sensor if there is problems with the EGR valve. A lot of the time the smell is like rotten eggs when you have a bad EGR.

Sensor code P0404 -- emissions system


P0404 EGR valve problem
Change the Exhaust Gas Recirculation valve.
This valve puts some of the exhaust gas back into the engine to cool combustion (to reduce spark knock) and lowers HC (emissions).

Check engine light


P0041 Downstream Oxygen Sensors Swapped From Bank To Bank
How does a P0041 code trigger the check engine light? This code will trigger the light to come on under the following condition:

The Heated Oxygen Sensor Monitor, a strategy built into the computer, determines if the Heated Oxygen Sensor (HO2S) signal response for a change in fuel trim corresponds to the correct engine bank. If a response from the Oxygen Sensor being tested is not indicated, a trouble code will be set and the MIL (Malfunction Indicator Lamp) will illuminate.
Possible Causes:
Crossed Heated Oxygen Sensor harness connectors
Wiring swapped from one Oxygen Sensor connector to the other
Wiring changed at the computer connection or in the related harness

1994 Buick Century [four cylinder engine]


You might have your computer checked to make sure the circuit that controls egr valve is working.  On my vehicle, I had several egr valves changed and failed the emissions test until I had the computer changed and the PROMS updated with the latest PROM.
The EGR valve is easy to change because it is on top of the engine.  It has electrical coils that control the valve and one of the valves may be damaged where it can not compensate at idle.  If the EGR is working, when the engine first starts the engine should increase in idle speed and then switch to a lower idle speed.  This is part of the EGR system check and it adjusts as the engine increases in temperature.
There are several other reasons if one of the Emission sensors is faulty that may cause the rough idle.  The oxygen sensor, tempearture sensor, MAP sensor,...etc.  You may have a trusted mechanic attempt to read any codes on the engine.
