What would be the simptoms of purge control valve failure??

Now, I am getting code 35 which is this sensor and car runs rough. The idle speed (on my '93 Loyale) fluctuates between 1000 and 1100 RPM and just after driving goes to above 2000 RPM and drops to 1100 RPM . Also, there is some bad smell from exhaust. Is the problem with idle becouse of the failure of this sensor or can be also something else?

Thanks.

Purge valve failure can certainly result in poor idling, especially when the engine is warm.

 

Your bad smell from the exhaust is likely due to bad fuel (high sulphur content, probably). Change to a different gas company. Keep trying different ones until the smell goes away. If it's available in your area, try an Ethanol blend.

 

I stay away from Shell, Exxon, and PetroCan because of the exhaust smell. On the west coast, you may have different results.
