1999 Lexus Rx300 Check Engine Light Blinking. The contact stated that the vehicle would not start without the diagnostic code reader. When i got off the freeway the car was also idling rough.
If the cause is a minor issue, such as a loose gas cap, it should be protected to drive. I just bought a 1999 lexus rx300 2 days ago and i took my sister for a ride in it the night i bought itand i drove over a speed bump going very slow and next thing i know the check engine light is on. I took it to an auto part store and they said the code is a p0446 and they dont carry the part so i need to go to the lexus dealership.
