I have a Dodge Charger Road & Track edition 2014 Model. I’m having two issues with the car
1) Rpm goes up & down on all conditions. Like even if i press the accelerator on park the rpm is still very very slighty moving. Not too major the car runs fine no vibrations or anything but you can definately notice the slight rpm up and down when you look at the guage. I have cleaned the throttle body still have the same issue. My mech told me its a vacum leak somewhere. How do check for such leaks?
2) If i accelerate the car heavily the check engine light will start blinking but will go off itself if i press the brake & accelerate normally. The odd thing is that the computer is not showing any codes. Not even in the history, no present codes. Nothing its all clear. No misfire shown. No stored codes
All help will be appreciated !
