Okay so after a number of codes popping up in the past 3 weeks i'm still having trouble at least i think... all the codes ended up goin out on there own... (even if i don't have the CEL on i still scan it just to see if any are pending and usually there are) Anyway i've noticed at idle my exhaust seems to be a little (idk how to explain it) but it just sounds like its not burning fuel right or sounds bubbly. Kinda like a small belch or studder. lmao its true! it just doesn't sound right... I noticed this because i was checking on things since at idle at a stop sign my engine sounded like it was screeching something... idk if it was my belt or what (have no clue) so just wondering if anyone else had this or anything. Thanks

 

bump for some help here....
It only does it every once in awhile... when i get it to do it (make the noise) its usually on the road and i can't just pull over... cuz as soon as i hit the gas it'll stop making the noise and doesn't come back for awhile

 

bump just encontered the same problem tonight right after jumping my car...

its hard to explain, it feels like a V12, it vibrates so much it is out of control

 

geez... take it to the dealer man, sounds pretty seriuos
