Dragging brakes would be noticeable by one or 2 wheels getting VERY hot.  And you'd probably notice the drag if you coast the last few feet before stopping. How common is gas-station fraud over there - maybe you're not getting as many liters as you're paying for?? How about a flaky odometer?  Can you check it against km-markers on the highway? ps... couple more things to check & rule out. How about spark timing?  Retarded spark timing would produce serious loss of power while still being smooth & maybe 'feels' like it runs OK. How about camshaft timing?  How long ago did you change timing belt?  Are you sure it's timed?  Take off upper timing cover & check whether it's still OK. < Message edited by JimBlake -- 4/17/2007 10:29:57 AM > _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to miks) Post #: 8
