Drove 700 or so miles yesterday and today. Topped it off at the end of the little voyage and it ran rough enough briefly while idling to shake the car. Started up fine, idled fine, briefly rough as hell and then back to...normal I think. It was as rough as a clutch chattering when you don't give enough gas. Only drove it 1/4 mile after that. All has been well with the car, I did do one quick pull up to 125 and shut it down a few min prior on a long lonely stretch. I think that's the only time I've had it over 100. WTF was that? Car has about 29k miles on it. Oh, recall not performed for the purge valve. After folks had been having issues with the reflash I have been hesitant to get it done.
