Hi.

I have a Lexus is250 2011
The car has some misfires without any code.
Cold start is ok and after 2 minutes it starts to misfire on cylinders 1 and 5 randomly like 1-3 missed and back to 0 (on OBD scanner) until I put it on drive and it stops misfiring.sometimes it misses in the stoplight and if I leave the brake pedal and press it again it stops misfiring.
Some days the car runs okay with no misfires at all And someday it misfires only at one stoplight and is gone.

I replace all the spark plugs but it does not fix the problem.
I am thinking of replacing the ignition coil.
