Re: Engine light flashing, strong sulphur smell, can feel...
If your engine light is flashing and sulphur smell engine power loss your probably looking at a catalytic converter.However you will need to have a engine scan completed to see what else is wrong as well.

When your engine misfires fuel is still being pumped into the engine, it's just not being ignited. You need to find the cause of the misfire first. It could be: a bad sparkplug, a bad sparkplug wire, a leaking head gasket, a bad ignition coil, or cracked engine block. I'd start with the spark plugs first, then the ignition coils as they commonly fail. Good luck!
sounds like cat converter just about completely clogged and the back pressure from it is choking the vehicle causing the cylinder failure --the exhaust cant escape and will kill [stall] the engine--- with it running feel the exhaust coming out if there is barely any flow from tailpipe cat conv has failed [clogged ] and will need replacement -----when check engine light flashes it is to advise that u have a malfunction that needs immediate attention or further damage may occur and or vehicle shut down may occure
Got a check engine light? Get the codes read to find out if the misfires are on all cylinders or just 1. Could be ign coil, bad crank or cam sensor, or a valve issue
You don't mention what that smell is reminiscent of?
You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?
You don't mention whether the road behaviour/performance is normal?
White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.
Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.
Burning oil smells a bit like burned eggs in the frying pan.
If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...
sounds like a restricted catalytic converter. you must, however find out why it got restricted, or it will happen again, from the sulphur smell, i suspect engine is running rich. you need a pro to help you with this problem.
Did you change fuel filter? Is there a check engine light on? Does it smell like sulphur? Check for vacuum leaks,bad egr valve or plugged catalytic convertor.
hello drk...the only time you smell this is when the engine is under a load? Does is seem to be coming from the a/c vents? Any smoke? I've never heard this complaint on the 2005 6.0 powerstroke. A strong coolant or sulphur smell is what most owners report.
Could you give a little more detail please?
light flashes when comp. picks up a skip pull code and it will be po300 random miss p0301 p0302 p0303 p0304 all are for that # cyl that has the miss best bet change wires and plugs check for oil on wire to plug end in spark plug hole leaking valve cover gasket or spark plug tubes...
