Re: 2000 echo check engine light
I drive a 2000 Toyota Echo!
I have a very similar problem but my engine says that my fuel mix is too lean not rich. I am going to try this because I just spent $250 replacing my O2 sensor and the problem did not go away. I'm so worried now because when my car is warming up for about the first 10 minutes, I have no acceleration and when it does its a really jerky ride and the car just seems to be driving funny. You said the MAS was to blame, is it simple enough for me to replace the part myself because I can't afford to take my car back into the shop again!
