A rich-running engine in a 1997 Dodge Neon can be caused by several factors, including a malfunctioning fuel injector, a faulty mass airflow sensor, or a defective oxygen sensor. Additionally, issues with the engine's air intake system, such as a clogged air filter, can contribute to an improper air-fuel mixture. The smell entering the driver's compartment may also indicate a possible exhaust leak, which should be addressed to ensure safety and proper vehicle operation.
The answer to the riddle "What is cold when it is running and smells when it's not" is a refrigerator. When a refrigerator is operating, it keeps its contents cold, but when it is turned off or not running, food inside can spoil and emit unpleasant odors.
Very likely.
because of the exhaust
You are probably leaking anti-freeze
A car heater that smells like burning rubber could be an indication of a belt that is slipping. The slipping belt smell can be drawn in from the engine compartment into the passenger cabin.
most likely your catalytic converter
If you have a motor other than the car such as a lawn mower in the trunk it smells. Also if you just got gas it smells.
take off the E-brake dumb@$$
Could also be that your car is running to hot (over heating). This can sometimes be mistaken for electrical wires being overloaded , and getting to hot. Check thermostat, and condition of coolant....
It probably smells a bit of oil when running but any smell of burning is a sign that something is wrong and it is liable to catch fire.
It could be a dead animal somewhere in the engine compartment. May have even possibly gotten into the A/C hoses.
this happened to me for about a month before i first got my period. so yeah your probably getting your period. but don't be to happy about getting it. haha it sucks!
