Stalling ford ranger

Hi there:
Normally the sulfur smell comes from the catalytic converter make sure the vehicle is running properly and not missfiring or running rough. Try cleaning the Mass airflow sensor heated wire if it is causing the vehicle to run rich it will start emitting different smells. Check for any debris that could be melted on the exhaust system and is burning off like a plastic bag.


You may have plugged catalytic converters.

Thank you for using FixYa, have a nice day.

There are a few things to check, first make sure all sparkplugs ,plug wires are good, in other words make sure engine is running smooth, a misfire will cause the smell and stalling so make sure tune up is not the problem first.

The next thing to check would be make sure air filter is good and throttle body is clean.clean the plate and body around the plate, the oxygen sensor can also cause this problem and is often forgotten about, the last would be the idle air control valve that control idle , there are more things that can cause your problem but start with these.

The most common problem may be as simple as the coolant temp sensor, this sensor if giving the computer a false signal with wrong coolant temp then this will cause this problem also.

A scan tool or multi- meter would help in testing the coolant temp sensor. hope this is helpful, good day.
