just to start this is about my other halfs 206. about ¾ days ago it developed a sort of chuggy/knockin when ever you lift off the throttle.
driving along would be fine but as soon as you back off its there. in gear is worse but its still evident when coasting along i have changed the gearbox for a secondhand 1 and same problem had the old box apart and discovered 1 of the planet gears was shot so replaced it and inspected all gears etc put the box back in still there now just changed driveshaft no change starting to get annoyed with it lol
