Hi,

For the last couple of days I'm having excessively low fuel mileage (8 mpg!). What do you think the cause might be? I've got this 854 two months ago and it has ~97000 miles on her, and as this is my first car I don't have ANY idea what might cause this. I think the last oil/spark plug? change might be at 90k (the guy I've bought have been a bit harsh on the car I guess). Do you think the reason might be the spark plugs? (if you do which spark plugs do you recommend, the car is non-turbo). I've put fuel system cleaner 2k ago I don't know if this might be related to that. But even my wife realized the lack of performance. Need your advice. Thanks in advance.

TODAY I'VE CHECKHED THE FAULT CODES AND GET NOTHING EXCEPT 1-1-1. tHEN I'VE FOUND OUT THAT THE AIR INTAKE DUCT TO THE AIR FILTER COMPARTMENT WAS DISSONNECTED AT THE BOTTOM OF THE COMPARTMENT. dO YOU THINK THAT MIGHT HAVE BEEN THE REASON FOR MY EXCESSIVE FUEL CONSUMPTION? I'LL DRIVE FOR A 20~ MILES AND CHECK BACK THE CONSUMPTION. KENNY, I'LL ALSO CHECK THE TIRES FOR HEAT AFTER DRIVING. ONE MORE THING, I WAS NOT ABLE TO GET ANY (NOT EVEN 1-1-1 OR ANY FLASH) FROM THE INGNITION SYSTEM (A6 SOCKET). HOW DO I LEARN IF I HAVE THE JETRONIC 3.2 OR MOTRONIC INJECTION SYSTEM, THE ENGINE IS B 5254 S NON-TURBO 20 VALVE.

LAST OF ALL, THE OLSD OWNER WAS SO HARSH AND INDIFFERENT TO THE CAR THAT, IT HAD 195/60/15S ON THE FRONT AND 195/65/15 TIRES ON THE REAR WHEN I BOUGHT IT!
THANKS IN ADVANCE FOR ALL THE COMMENTS.
