Hopefully I will not encounter this problem again. I just had the HPFP recall, injectors, and plugs done.

LOL what? That's like telling someone who has experienced stumbling around 3.5k rpms to 'just keep it below 3.5k rpm, problem solved'......Really?

In my experience this is due to bad quality gasoline. After using better quality/higher octane fuel the problem went away.

If you had plugs under warranty, then you're in the 45k range. I would expect to see some good carbon buildup at that point. Has that been addressed?

rosskie · 09-10-2011, 12:36 PM
