Curious to know if anyone has dealt with the same issue I’m having. After getting gas the other day, I went to drive off it randomly started to shake and make a weird noise. Acceleration felt a little weird. I pulled over and turned it off. Turned it back on and the problem went away. It started with no issues either time. A few days later I was stuck in traffic and it started to happen again. Ended up having to turn it off on the highway because it wasn’t going away. Started back up with no issues again. After turning it off and back on, I felt it start to happen again and accelerated to see if it would stop it from happening again and sure enough, the shake stopped. No codes and it doesn’t happen all the time. This is my daily commuter and nothing seems abnormal until it does that. I’m starting to think it may have been bad gas? Would it run rough constantly if it was bad? It’s a 2006 GT manual with 154,000 miles.

 

If you post this in the 2005-2014 mustang section you're likely to get more responses, wish I could help you out but I don't know much about the newer mustangs.
