I have an 01 IS 300. The Trac Off light started blinking last week. My check engine light is on. I took it to the dealership and was given codes P0440 and P0441. They recommended that I change the battery, which I did. Now the car sounds like it's going to stall or completely shut off. Any suggestions?

 

Those are both evap system codes. You can search on here to see what all it may be that is causing one/both of those codes. More than likely if you fix one, you'll get rid of the other as well.

The trac off is blinking because it is shut off when you have a CEL.

 

I appreciate it! Thank you!
