I have a 2002 TS Wagon. After filling up and starting the engine/ or turning off the ignition and re-starting quickly, theres a strong sulphur smell out of the exhaust.

Anyone know what is causing this? The dealership service dept said hard driving will cause this, and blamed it on the K+N Drop in filter I have.

 

it may be the extra airflow from the filter is cause a rich condition, (I am saying this w/out knowing much about the engine manangement sys for subies) the extra fuel could be too much fuel for the engine to burn and sending fuel out of the combustion chamber on the exhaust stroke and forcing the Cat to work overtime. If this is the case the cat will eventually fail. There are some cars that smell like that normally when they are running rich (ie. warmup, goosing the throttle while in a high gear on an incline) I have noticed a lot of Toyota's stink like *** when I am behind them on the highway.

 

Hi grknss:

Thanks for the reply. Would the car's computer not adjust for the extra airflow and compensate?

 

thanks. Suby_tech. They ran the diagnostics at the dealer and said everything was fine...they pointed out the K+N filter was not seated properly and that hard driving may cause that. Will keep an eye on it.
