Art Aparicio Posted January 25 Share Posted January 25 My 2019 Lexus RX300 had check engine light come on and I felt a rough idle. The car accelerated without any misfire cruises without misfire. My OBD reads code P1354 Ignition system misfire. I also notice that braking takes longer to stop at the same time. When I erase the code, the car runs fine. No missing and no braking problem. After about 1/2 hour of driving the engine light comes on and the same thing happens. e.g., rough idle and weak braking. Quote Link to comment Share on other sites More sharing options...
