ok guys here it is. my check engine light came on in my 1999 c230 komp. i then noticed a bog down feel in the engine like it didn't want to go. then i came to a signal light and it was sputtering. it has done this for a couple of days now. sometimes even when i try and gas it real hard i get that loud back fire noise. whats real funny is that when i turn the car off then on its gone fore about 5-10 minutes and the car runs fine but its getting worse each time. is the the maf that i hear about?
