Guys I'm having the following problem, I have check engine light on and after I scan for error codes I receive:
Activation, ignition coil, cylinder 1
Activation, ignition coil, cylinder 2
Still the car runs fine, without issues.
After I erase the codes and let the car idle (no check engine light) in a few minutes 4-5the check engine comes back on and I can hear a small change in engine tone just when the check engine light comes up, after that the idles fine.
