Anyone got any experience of this please? My 115,000mile 2010 CR-V 2.0L Auto petrol has developed a rapid shuddering/vibration when in 4th gear (auto) coasting/pulling slightly at low revs - about 1300rpm, 22mph. If i accelerate and drop down a gear (or use the 3rd gear selector button) the vibration ceases. It's only there when the engine is "lugging" slightly at low revs, and disappears at higher speeds or in different gears. Main dealer has tried changing plugs, and then replacing the main drive shaft which was a £900 expense but hasn't solved the problem.
