Have a 2011 SS 6speed with magna charger. Has 5400 miles. Started car, 1st drive of the day. About 15 minutes of driving on high way I get to 5th gear and notice car starts to buck as if it's loosing power, then it kicks back in. Downshift to 4th, 3rd, 2nd and it starts to buck and jerk again at about 20mph. Noticed the buck and jerk in about every gear. Seems to get worse. Idles with no issues. No check engine light. Kind of bummed out about it with such low miles. Any help would be appreciated

Did you set off any codes sound to me a coil bad or a loose spark plug wire but could be other issues aswell.

ClosequarterHSV · 08-31-2014, 09:36 PM

No codes. I've checked spark plugs visually. Had that happen on another vehicle before. Wonder if fuel filter is dirty or needs replacing already.

Lance455 · 08-31-2014, 09:40 PM

Think the fuel filter is in with the fuel pump on the 5th gen. Which could be the fuel pump they sometime fail prematurely at least what I seen on a few buddies of mine. vehicles

Ok. It never did this till today. Wondering if since I have stock fuel pump with magna will that make a difference. Am going to install a zl1 pump and module but I was hoping this issue would be a simple fix.

So I put another gas station 93 in and haven't noticed the problem. I got excited and did a quick burnout and directly after it started sputtering and cut off a few times. Started up with no problem first 2 times then cut off again and had trouble starting but it did...back to the drawing board

Tuning issue?

hunter1660 · 09-02-2014, 12:25 PM

Sounds like it's starving for fuel....once you start it and it builds pressure it runs great...once you bleed the fuel off its starving to maintain open throttle, but idles....don't think it's gonna cure itself...you need to see what kind of pressure your maintaining at the fuel rail

Thanks for your replies. It means more than you think. Having a new car and then these issues is really frustrating. I have a tune appointment hopefully tomorrow so I'll keep you posted. Hunter I'm thinking so!

Got in car this morning to take to tuner and now check engine light was on(Good thing so i know where i can start troubleshooting) p0101 i think was the code--Said mass air flow sensor low---I open hood to check it out and my MAF sensor was not snapped in all the way. I snapped it in and heard a difference in sound. Cleared code and now will test drive today. Im hoping that was the rootcasue of my issue.
