Toyota Repair: engine lights, 2004 rav 4, traction control

Question
I just bought a 2004 Rav 4 - love it!  However, the check engine light and VSAC track light keeps coming on and the dealer has been unable to fix it.  They have already replaced the gasket in the intake manifold.  I am frustrated!!!  Any ideas?

Answer
Hello Cecilia, welcome to my expert page.
In order for me to help at all I need to know what diagnostic trouble codes (DTCs) are stored in the computer, The vsc and trac warning lights come on because the check engine light is triggered first, this will disable the vsc and traction control functions and turn on these lights as well even though there may be no problem with these systems, please, in order for me to have any advice for you is to know the trouble codes."all of them"
