Yep I have run shell vtech 93 octane for the last 6,000 miles. I still feel the kind of misfire when gently passing through 42 mph.Yeah, I'm sure its FCA choking the motor, not the 300-1000lb weight difference between the Avenger and the Wrangler. Or the massive tire size difference.
A lot of these problems sound like detonation/octane is too low. I know the 3.6 is designed for low grade, but does anyone having these problems run premium?
