I replaced drivers side header gasket the night before all this went dow, must have screwed the pooch when putting the wire back on and just neglected to pay proper attention to the position. Doubt that was the shake. 1) my luck doesn’t run like that, and 2) it wasn’t a miss. She was running good. This was definitely front end. Thinking even like Frank mentioned possibly brake induced. Was also noticing like a brake drag in gear at an idle. Going to look at brake system also just for piece of mind. Oh and not a fan of plain vanilla shakes. More of a full blown chocolate malt guy!
