Hi. I’m a owner of a (new to me) 2006 Range Rover Westminster (#36/300) with the 4.2 supercharged V8 and have been enjoying it. Lots of little issues to sort out but always drove well. Ran awesome one night and the next morning was shuddering and missing. Gave me a reduced engine performance...
Ok i have a 2004 RR HSE, 135000 mi i bought used and have did work to now im getting P0301 constantly with no sign of cure help if you can.
Past 2 month and 2000 miles:
8-bkr6equp spark plugs
valve cover gaskets
Had slight oil leak, replaced line...
