Shogun V6 Auto SWB.
Engine Check light comes on and goes out regularly.
Dealer has checked but can't find anything to fix.
Occurs most on cool wet days.
Normally ok on warm sunny days.
Suspect Oxygen Sensor so changed it.
All ok for a while than same symptoms again.
Fuel consumption increases when this is happening.

Anyone got any ideas please, and many thanks in advance if you can help.

hey there from jet black, just had the same problem as your having. went to my local garage and it was the air intake sensor at a cost of £65 to put right. was also lacking power before, now goes like s#it off a shovel, no more light showing and fuel consumpion better. Hope that this will be the answer to your problem
