Hi, This is my first post: I did not know that Saab has so crappie spark plugs. My previous car was a Chevy Cavalier 96 from 0 miles now has a 100K. When I changed the first set of spark plugs at 60K, even though the manual said every 100K, on the Chevy they were like new. When I got my Saab 9-3 '99 with 36K mile I thought it has the same king of plugs, without consulting the manual (who reads the manual anyway). So with that in mind, day before yesterday my Saab started to cough in the lower rpm, with every shift. I said myself: maybe is the muffler that I replaced last week, maybe not. I checked the spark plugs and I could not believe: they were toasted, the hook that comes around was almost gone completely on all four. So, because I could not find Bosh I went with the original NKG crap....Needless to say the Check Engine light came ON, so I had to disconnect the battery for 15 minutes to reset it. Anyway getting to the point: now, after changing the spark plugs everything seems to be OK, but my gas mileage went from a 25.5 mpg (at least) to a 24 mpg (at most).....!?!!??? What can it be wrong???
