CEL
 

Had a tek 3 yesterday all went ok.On the way home the car missfired under heavy load in 3rd and put up the check engine light.The light didnt stay on.Took the car out today,driving 20-25mph cel flickerd again and went off.Checked the fault code which was diagnosed as code 22 knock sensor.Do i replace the sensor and do a reset?? or is it tek3 related/coincidence.
The car still drives fine,advice would be appreciated

check with who mapped it sounds like possibly detting..

not good then:o

I phoned soon as i got home and was told to keep an eye on it
