Question about Dodge Cars & Trucks
I have a 2002 dodge neon that just started to smell like rotten eggs or something died in it but the car still runs fine what could it be can anyone help
Does your car have AC.... ? ac problems can make a eggy smell also a damaged catalytic converter do the same. eggy smell can be the gas from the ac leaking out. you would need to have this check as it can do harm to your lungs..

Hey there riddick,
That rotten egg smell is a problem with your catalytic converter. Too much back pressure is not allowing your engine to run normally.
I'll bet its been getting hot too.
Warning: For your own safety, until this is resolved, do not look under or stick your head under the car with the engine running. I've been in a vehicle when a converter with these same symptoms blew apart at the seam. Made my head hit the roof. If it happened a few minutes earlier I would've gotten a faceful of freshly flattened converter. So be careful.
To tell for sure about the problem, try to get it to an auto parts store that does free code readings from your On Board Diagnostics. There should be errors referencing the engine, O2 sensors and emissions. The exact diagnostic codes with determine your next course of action.

SOURCE: Car died rotton egg smell
Not sure if engine coolant smells like rotten egs when it burns inside the cylinders , but it sounds like you may have blown a head gasket. Coolant and/or oil could be getting inside combustion chamber. Another possibility is that the catyletic converter might have broken up and colapsed onto the screen where it goes into the exhaust. Might give the rotten egg smell and block the exhaust enough to cause backpressure sufficient to cause the engine to run poorly too.
Try putting your palm over the exhaust pipe , if the exhaust is coming out in pulses (pop ,pop,pop) thats normal , if it is just slowly flowing out with no noticable pulses , I would check into the cat converter problem.

Your catalytic converter is plugged up,
If you check the exhaust output at the tailpipe you will find it restricted.
Let me know if I can assist further.
