Why is my Lexus IS 350 not working?
The IS 350 uses both port and direct injection, so it doesn’t suffer from carbon buildup as much. A rough idle may indicate a carbon buildup problem. To test this, you’ll need a bit of space to get up to speed: Drive the car up to at least 3rd gear. Without slamming on the brakes, depress the pedal hard enough to come to a quick stop.

What does a check engine light on a Lexus mean?
If the Lexus has been misfiring for long enough, it will have probably thrown a check engine light. The light means the Lexus has a diagnostic trouble code stored on its ECU. An easy way to retrieve those codes is by using an OBD-II scanner.

Why does my Lexus engine keep misfiring?
There are certain self-diagnostic tests that you can perform to help determine if you need an engine rebuild or, for example, just need some new spark plugs. Misfires on the Lexus are most commonly caused by carbon build up on the intake valves that has flaked off and becomes stuck between the valve and the seat, causing a loss of compression.
What are the P-codes on a Lexus RX 350?
If anybody tells you that you have no codes, without hooking up their scan tool, go someplace else for service. Second, the intermittantcy of this leads me to believe that, when you do get the car scanned, you may find some P-codes, P-0440/P0446.
