I have a 2001 VW Beetle, manual transmission. I know that it has one bad 02 sensor. It has occasionally lugged down when accelerating, particularly from a stop. Meaning that I gave it gas, and more or less nothing happened or it was super slow to react. It was only doing this when the AC was running; now it is off and on at seemingly random. It was stuttering/stalling at start up the other day, but wasn't the last few days. It also just began making a noise somewhere between a clunking and popping that sounds like it issues from roughly under the driver side seat/well area, today.
What are my likely candidates and where should I start? Thanks, guys.
