I hope the competent members of this forum can help me.
All advice will be appreciated.
My 4/4 has a very rough running between 1800-2000 rpms. It seems it gets worse in hot weather or with hot engine. I think it has something to do with the ignition as it feels the same as when the spark plug voids were filled with water after washing my car.
The engine management light comes on. When I use my OBDII reader it states code P1131. I replaced both coil pack and leads in 2018 which improved performance but the rough running remains the same.
