Rotten egg smells

Why would my car smell like rotten eggs. Also when I've drove about 20-30 miles it sputters & dies. Once I let it cool down it will start again & drive for a little while b-4 starting to sputter again. I've changed the thermostat, spark plugs, brand new battery, air filter, oil change 7 filter.

Rotten egg smell normally comes from a failing or faulty catalytic converter. To me your symptoms describe that. Changing that should aleviate your problem

John, I will save you some money, I just took my 94 ranger with the same problem to the dealer and they fixed it. They replaced the ignition sensor and the fuel pump sensor and a O2 sensor. The ignition and fuel pump sensor is in a fuse box right behind the battery. They are a 1 in. black pull out cubes. Ask a parts store which ones they are. Numbers are stamped on the cube.

The rotten egg smell is a dead giveaway that your catalatic converter is bad. This could also be the cause of your misfirie condition. Take to your mechanic to have the converter replaced and this should correct your problem.

You may have a fuel leak. when there is odor of gas there ia a leak somewhere. Pop the hood and check with your nose where the smell is coming from. Once you isolate the location of the odor check with your hands. if your hand is wet and smells of gas you have found the leak. Next get a mirror to see if you can replace the hose yorself. In some cases due to the age of the car and since most fuel lines are made of rubber, after some time they can become corrosive and start to leak. Check the fuel lines. If the smell is entering your cab while you drive the problem is in the front of the car due to the fact that as you drive the rushing air will cause the odors to dissipate. Good Luck!!!

1993 LS 400. Starting out the car just is slow. It's not the tranny. Tranny shifts perfect including reverse. I smell gas. Old lady drove car the whole time. 118,000 miles


IF WHAT YOU SMELL IS RAW GAS THAT IS AN URGENT PROBLEM THAT SHOULD NOT BE PASSED OVER. IF YOU SMELL A ROTTEN EGG SMELL THEN YOU MIGHT HAVE A CATALYTIC CONVERTER PROBLEM THAT GIVES POOR ACCELERATION. CHECK FOR FUEL LEAKS AND CHECK FOR ENGINE VACUUM AT IDLE. MUST BE AT LEAST 19 INCHES,. IF NOT, YOUR CONVERTER IS PLUGGED.

Why does my Navigator smell like rotten eggs and misses when running?


Because you fail to do routine Preventative Maintenance

You do not change spark plugs every 3 years
Front oxygen sensors at 100,000 miles
Remove & mail your injectors away-- for Ultra Sonic
Cleaning, at about 150,000 miles or 12 years

Now the exhaust converter is ruined,thus the rotten egg
smell (sulphur dioxide) also from failed cop ignition coils
& thus rich fuel trim & ruined converter

Lost of work needs to be done there, before you can replace
the converters

It will take $1,500 min to straighten out those issues

Initially ran rough blew blue smoke from exhaust, smelled like rotten eggs and died. After several starts it kept running fine until 15 miles down the road the engine killed while at highway speed. After...


If it's blue smoke, your burning oil. Get the head gasket checked. If that's ok your looking at something more serious, (more expensive), inside the engine.

What's your problemm?chevy colbalt smells like rotten eggs


The rotten egg smell usually occurs from time to time. It comes from the battery being charged by the alternator. However, if it smells continuously there is a problem. It's likely that your alternator is overcharging the battery. This needs to be looked at soon. The alternator will need to be replaced or repaired. Hope this helps.

Car runs ok, but gets hot and rotten egg smell comes out of the exhaust


If car runs okay with egg smell, its normal and working the way it should, if car is running poorly and the rotten egg smell has gotten worse, its a sign that your exhaust catalytic converter will need to be replaced. good luck!
