I had somewhat the same problem but it eventually triggered a cylinder misfire. Bad coil pack. Sounded and felt terrible with all the bucking and shaking...couldnt get past 60mph! It took over a week for the code to finally show up
. I have since replaced them all (like lightbulbs..if one goes bad, change em all!)

check the alternator too! When mine went bad, very weid stuff happened. But never a code.
