2008 Dodge Nitro flashing check engine light

my engine lights dings flashes then stays on then dings flashes n stays on

Get to a mechanic ASAP for diagnosis and repair. If the CEL is flashing, have the vehicle towed

Have the car towed to a mechanic, do not drive it.

A flashing check engine light means that further running the engine may do major damage.

When did you last check the level of the oil, and did the engine recently over heat???
