Hi,
Im wondering if someone had a similar problem knows what could be the reason for the sudden misfiring of the engine in lexus gs450h. The failure occurred suddenly at a speed of about 50mph the engine suddenly lost power and began to work unevenly as if was misfiring. It sounds like a diesel now...
The car was towed to a mechanic, hooked up techstream and error P3090 Camshaft Position Sensor 'B' Circuit Bank 2 popped up. The mechanic said that maybe it was the spark plugs and not the sensor and replaced all the plugs, but the problem remained.
The sensor will arrive after Christmas and will also be replaced, but I do not know what to do next? The mechanic said that it could be a pulled timing chain or jumped one tooth and he doesn't know really lol
Has anyone of you had a similar problem ? the car starts engine without eny problem but it seems as if it is not running on all cylinders. Mileage is 168k.
What else should be checked to try to remove this fault ? Anyone knows any good Lexus mechanics in Hertfordshire ?
I am attaching a video of the engine running
