Default Rough idle?

Problem started yesterday night randomly while I was driving. I noticed as soon as I let my foot odd the pedal the car began to shake slightly while coming to a stop. The car accelerated fine without a problem it was only when I let my foot off the gas where I noticed the vibrations. When I got home I put it in park and the car shook harder and I heard muffled popping from the exhaust. Anyone know what it could be?

Can't be the gas. Been usuing nothing but Shell VPower since I bought it without a problem.


I was guessing it was misfire also. Gonna get it scanned in a bit and see what code pops up

Turns out to be the VVTi sensor failure. Which is also causing cylinder 1, 3, 5, 7 to misfire

Do you happen to have a part number?

How hard would this be for a novice?
