Hello everyone! I have issues with my lexus is 200 (1999, 1G-FE), the engine vibrates under acceleration, has misfire in cylinders number 1,2,4 and feels like it's in LIMP mode . Stored DTCs- Lean mixture bank 1, misfires in multiple cylinders. Car runs fine and has power after reseting ECU for first 5minutes then Engine and TRC lights starts to flash and it looses power. I've tried to clean throttle body, checked fuel pressure, checked injectors- cleaned them, replaced both o-rings, tried to swap their places but still shows misfire in cylinder 1,2,4. Tried to switch coil pack positions but nothing changed( Their body is cracked), checked PCV valve, checked all vacuum lines, tried to block vacuum line from brake vacuum booster and block it but the problem is still there, I've no idea what should I do next.
