Check Engine light with Vsc and trc control light on
Hi I have a 06 is350 and need help with this problem...
In the past, the check engine light/ check vsc light/ traction control light is on... I didn't do anything and waited 2 or 3 days and it went away. Hasn't come back for months.
It's back now and I was wondering... Could it be that I need to clean my MAF sensor?
I'm running a K&N air intake.
Also my RPM does some weird movement especially when I brake my rpm will go down then suddenly it will jump back up and then settle back down. It SEEMS like my car adds a little bit of gas when I brake sometimes. I'm not too sure
If i need to clean it... do I use the CRC maf cleaner? I heard it was not to be used on "some" lexus cars.
Any input on how to fix this problem? thanks alot

Bro I just had the same problem last night, and solved it I have a friend with an OBDII tester and the code was P0174 which is running too lean, and I remembered the night prior I had just installed a JoeZ and the vacuum hose from the engine to the tube wouldn't fit tightly and it came off and that gave me the code so reclamped it with a much better tighter clamp and cleared the codes and done and fixed... Run a tester at any autozone and see what codes it throws and go from there it could be the MAF or just a leak from that vacuum hose

Most likely a clogged evaporator charcoal canister, especially with that many miles. Never a good practice to top off the when file up (the excess gas will run into the evap loop).
Good luck and let us know once you got it fixed.

Google "Lexus Evaporator and P0456" and read up on it. Yes, most likely you will have to bring to the shop for it unless you are handy and a good diy. The parts will cost you around $200 so I would just change them if I was you (of course I do fix most of stuffs on my cars).
