What got me looking was a very light surging stumble during light acceleration ...checked everything couldn’t find anything ..changed plugs no change I thought the fuel pressure might have been bouncing causing it ....it is only under light throttle and very minor ..it’s around when the vacuum gauge is from 5-0 when I’m cruising at a steady speed .....no issue during boost
