Hi guys a quick one for you lot. When town driving my car is fine but when Im driving on the motorway at a steady 60-70mph my check engine light but the car still doesn't miss a beat no missing no holding back.The car was mapped Monday and is running maffless. Has anyone any ideas what it could be causing it . thanks phil

Could be anything? Maybe rear lambda as at higher speed there is more gas flow so that could bring it up.....

Presume was ok before being mapped? Go back to mapper and ask them to have a look.
