'00 S70, non-turbo auto. 196k miles. Intermittent stuttering/shuddering under mild acceleration. Check Engine light has come on. If it was carbureted I would say it feels like its fuel starved, or a vacuum leak. Before I get the code checked, what do you think?

 

My daughter went over a pothole and the check engine light shut off!

 

and my wife goes on to say that my daughter braked hard on the same trip - and the Check Engine light came back on! I couldn't make this stuff up.

 

Maybe I can diagnise this myself...What are the codes for ETM failure?

 

Yup, yellow code that ETM is going. Gently dying, according to the mechanic.

Wonderful.

 

Maybe it's the ETM.
