Hi

Your battery is shot, the plates inside are possibly shorting out.

New battery I am afraid.

Good Luck !

P.S. Don´t forget to give me a rating please !

When running, the Navigator has a rotten egg smell and misses.


The rotten egg smell is because the engine is not properly burning and processing the fuel and exhaust gases. The first culprit to suspect is bad catalytic converters. But since you are also experiencing misfires you can probably start with a tune up. And clean the fuel injectors. You can try running some Techron through the gas tank. Then have your vehicle scanned for error codes. Most auto parts stores will scan your codes for you.

If your scan does not indicate anything and you still have the egg smell, you probably need to replace one or more catalytic converters.

Take a look at this video on how to try to clean catalytic converters before buying new ones...

Alternator burns out


You have a faulty battery, that's probably what killed the other alternator. The rotten egg smell is gases coming from your battery. Change the battery before you cook the second alternator.

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.

The rotten egg smell if it is coming from the exhaust is a very good sign that you catalytic converter has failed or is failing. but a bad or battery that is being overcharged can also make a rotten egg like smell.

Sulfur smell coming from my 2004 chevy colorado wont start unlss i jump it


You have a bad battery and it needs to be replaced. The rotten egg or sulfer smell is coming from the acid in the battery. I would not continue to jump the vehicle as the battery could explode.

Car runs rough when it does run. then in about 5 miles it just dies no power at all? the battery is new so is alt. new plugs and wires ? it just dies and needs a jump. soon as its off it wont start again...


Have your mass air flow sensor cleaned/serviced., then your catylictic coverter.you can chk but takes two people. one at the tailpe and the other at the key. The moment the engine is turned of, the exhaust shout stop.Using a tissue see if the exhaust continues bet in a drifting manner. Note any odor of rotten egg or sulphur smells. Listen for ant wheezing coming from the tail pipe while the engine is running. This is rhe more probable cause. Good luck -Ned

Engine light


The "rotten-egg" smell is caused indirectly by the catalytic converter. The main cause is a rich mixture condition from the engine. Your SUV is equipped with a computer controlled engine management system. You can scan your computer for fault or error codes. The information should pinpoint the malfunctioning components. There is an alternate reason for the rotten egg smell. this also can be caused by a over charged battery. if so, make sure the alternator isn't overcharging the battery cell. it will boil the contents causing the egg smell. I recommend a diagnostic run to make sure what this problem is.


please rate and god bless.
