Does it go out when you start it up?

With the engine off, try cycling the key from run (on) to acc (off) to run (on) to acc (off) to run (on) and see if the odometer shows any codes.

The "key dance" Begins in the ACC position.
ACC-RUN, ACC-RUN, ACC-RUN leave it in run at the end.
The whole sequence must be completed in 5 seconds.

The blinking check engine light with key in RUN with engine off
means that the system is not ready for emissions testing.
Either the car has not been through enough run cycles since a battery disconnect or there is an emissions related problem.

Make sure you plugged everything back in. It sounds like you may have left your map or maf sensor unplugged.

Hi rany e j,

I recommend letting an FCA dealership take a look at your rpm fluctuation concern. Keep us posted!
