What are the possible causes for a engine code of 41 on 1985 Oldsmobile?

The engine code 41 on a 1985 Oldsmobile indicates a problem with the exhaust gas recirculation (EGR) system. This system helps to reduce emissions by recirculating a portion of the exhaust gas back into the engine. When the EGR system is not functioning properly, it can cause the engine to run rich and produce excessive emissions.

Some of the possible causes for an engine code 41 on a 1985 Oldsmobile include:

* A faulty EGR valve

* A vacuum leak in the EGR system

* A blocked EGR passage

* A problem with the EGR temperature sensor

* A problem with the EGR control solenoid

If you are experiencing an engine code 41 on your 1985 Oldsmobile, it is important to have the vehicle diagnosed by a qualified mechanic as soon as possible. Driving with a faulty EGR system can damage your engine and increase emissions.
