Default Engine speed jumps up and down
Hi, I drive a 2010 5.7l Dodge RAM.
The engine speed jumps from 500 to 600 RPM up and down every 2 seconds.
The air conditioning is off and the throttle valve is clean.
Is that normal?


greeting
Christoph from Germany

did you just get it? If not, it's probably been doing it from day 1 and you didn't notice. Mine has always idled at 500 to 600 rpm. Mine is a 2009 hemi.
