IF it is Turbo charged then that would be the turbo.
There can be a slight humming noise while driving a neon. This sound could come purely from the engine to indicate that it is running.
Most of the time ,it's because engine is catching air .check for a hissing noise. a soapy solution in a spray bottle .while engine is running will find where the leak is .engine sound will change when you find the spot .
If the check engine light is blinking that indicates that the catalytic converter will possibly be damaged if you ignore the problem and continue driving the vehicle. i had a car in the shop here last week with that problem and it turned out to be a cracked vacumn hose. I lifted the hood and could hear the hissing sound from the vacumn leak . The crack was in the 90 degree bent hose connected to the PCV valve. This was a GM vehicle with the 3400 engine.
engine rubber mounts or timin out
if the sound of the engine cranking sounds unusual, your timing belt has snapped.
Why engine stalls on 1993 Chrysler Intrepid while driving and sometimes at stops?
Yes, but they do not have vocal cords. Their breathing organs (while breathing) emit a hissing sound.
Maybe its your motor mounts.
Is the engine running ? no
The loud static radio sound while driving is usually caused by an interruption in service. It usually happens when you drive through a tunnel or a remote countryside.
That depends on the engine and what belt (timing or accessory).
you have a control vacuum leak, listen for hissing noise under dash when engine is running.
