Strong exhaust smell from my kia sportage 2009


This is from incomplete combustion . The problem is that the injectors are squirting instead of atomising. Have the injectors tips replaced at a diesel pump repair shop.

My 2002 Kia Sadona has a bad sulpher smell and sometimes backfires. what causes this?


Bad sulfur smell is a classic symptom of a bad catalytic converter. This would also account for your backfiring problem. If you are experiencing extreme heat through the floorboards, this would be another indication of a bad Cat. A trip to a muffler shop for an evaluation should confirm this. Best of luck!

2003 Mitsubishi Lancer ES. First had code, changed both O2 sensors. Bad sulfur smell resolved, check engine light resolved for about 400 miles, then came back on. Same code, but the smell is still gone....


Probably a bad catalytic converter. Causing back pressure and making your O2 sensors read wrong. Cheap gas of less than 87 octane can cause incomplete combustion giving the sulpher smell and leave deposits in the exhaust. The sulpher smell originally came from fuel additives in your gas. Cheap gas especially. Your converter puts it out as sulphuric acid. This damages the sensors and converter. Ultimately though, what cause sconverter failure prematurely is idling your car for long periods. Over 3 minutes is not recommended.

My jeep starts and runs rough,it wants to stall but keeps running ,like it wants to bog out and keeps bogging?


I had that happen with a '99 Chevy Suburban, it turned out to be the catylatic converts were plugged. Disconnect the exhaust ahead of the "cat" to see if it runs better, just take the pipe(s) loose. Or remove the O2 sensor(s) so the exhaust has somewhere to go. For test purposes only!!!

Sperts of power


Hello! Your symptoms tell me that you likely have a catalytic converter issue. When the converter becomes clogged, you will experience a significant loss of power and torque. This is often, but not always; accompanied by the smell of rotten eggs, another tell-tale sign of a converter issue.

I hope this helps, and thanks for using FixYa!

2003 ford focus shakes bad when cold. Exhaust smells like sulpher.


The shaking can be dependent on the engine size and configuration. The sulpher smell is from the catalytic converter starting to work as it is supposed to. Your problem could be as simple as a cold start sensor not working correctly. Your vehicle may or may not have one, but it should have something like it to tell the ECM (engine control module) how to run the engine when it is cold. Newer vehicles also use a sensor in the air-cleaner to measure the temp of the air going into the engine and then adjusts the engines fuel, timimg and other functions to make it run correctly. Your best bet would be to have a shop put it on a diagnostic machine and check the engine systems operations. Most all newer vehicles are computerized for better engine and emission operations, so it requires a machine to check them out. Good Luck, RAC
