Ok when I went to start my 99 lesabre this morning it vibrated really bad and shook then it got smooth and the check engine light came on..I have started about 5 times since and it is not running rough anymore but the check engine light wont go off.....I replaced the spark plugs and fuel filter about a year ago...I just got the oil changed...I replaced the air filter awhile ago...I have 46,000 miles on it...can anyone tell me what it might be?

Maybe if you give us the code for the cel!

I dont have the machine to get the code...and the places I know charge like 80 dollars to check it...

Do you have an AutoZone near you? They will read codes for free. Make sure you get the numbers of the codes. Post them back here and we'll try to help you out.
