Lexus Troubleshooting Questions? Ask a Lexus Expert
Do you have a code reader to check for codes.set in the computer?
Has the check engine light ever start to flash? Sorry I had to step out on a test drive. If you don't have a code reader in most states except California Virginia they do free malfunction code reads. If you have the code numbers causing the check engine light to come on I can provide you with more input. I have to leave another test drive I will be back on the computer this evening pretty much full-time until 11 PM Eastern standard Time.
