Was under boost on my way home and when i did i noticed the check engine light flickering on and off. I immediately got out of it. It did not illuminate permanitly just flickered while under boost what could have caused this??

 

If the CEL comes on there's usually an error code stored. See which one...

I had that happen to me and it was my O2 sensor wire, just a thought.

 

Thanx guys it was the sensor wire fell on the downpipe.!!!
