Review Of 1999 Lexus Rx300 Check Engine Light Flashing References. There is a light clunking. The engine was not stable and the car behaved like carrying a ton or two of load.
Always read lexus engine fault codes using an obd2. Web a few weeks ago my 1999 lexus rx300 started running rough and using more gas than usual. Web although less common, if the air filter is blocked, it may trigger the check engine light with a p0172 code, signifying the engine is running rich.
