Not sure how to word this but recently my exhaust warning lamp has come on. It stays on for a couple of weeks then goes off. It doesnt go red and I dont get any warning in the MFD. At other times when Im driving I dont get any big power loss issues but on occasion it feels like the car is "pulling & pushing". Its the only way I can describe it. My missus who sits in the passenger seat doesnt feel or notice it but as the driver I can feel it. Any ideas? Are the 2 things connected?
