I have a 2004 toyota rav4.yesterday the vsc trac light and check engine light came on.the vehicle idles fine but when you depress the gas pedal there is alot of hesitation.

My solution is to get rid of this car immediately!! I had that happen to me. I had my mechanic check it and it was fine about 2 weeks later the car completely died because there is a defect with the 2004 Rav4 2.4l 4cyl. engine. Toyota never recalled this defect and now I am stuck with a car that is worth NOTHING. The top of the engine is put on with a metal/screw that is too soft. It separates and then antifreeze leaks out forcing the car to overheat. There is really no way to fix this besides dropping a new engine. I am stuck without a car and at a total loss. I will NEVER buy a Toyota again. Good luck!

This happens every year to my Toyota RAV4. Go buy a new gas cap. The codes ussualy come up that you need a cat conv or evap system. However, if you put on the new gas cap the lights go off. This is a common thing with 2004-2005 rav4.
