hey mine does something similar to that too!!! Sorry I didnt give an answer though!! Hopefully, someone will know how to help us on here. What I really want to know is how much it will cost to fix this sputtering-but-never-dying-vibration-while-car-idles thing.
Me too! 2006 Corolla ce Frankenstein body, bought it today for 1500 bucks with 162,000 miles runs like a champ save two things: electrical problem with one headlight and it vibrates when idles in drive.
