HI ALL NEW TO THE FORUM. I RECENTLY INHERITED A 1990 CADILLAC SEDAN DEVILLE IT IS A VERY LOW MILEAGE CAR AND PRETTY CLEAN. THE PROBLEM IS IT HAS WHAT SEEMS TO BE A MISS OR ROUGH RUNNING CONDITION THAT HAS GOTTEN WORSE RATHER RAPIDLY. I have checked all the plugs they seem clean and the only color to them is a light brown no sign of any carbon or fowling. I was wondering what to try next. any help would be appreciated. thanks in advance:hmm:
