Hi all looking for some advice please. My XF went into restrictive performance mode a couple of weeks ago, so took it to the garage I use where they found that the throttle body was cracked which was replaced and a couple of other pipes that had splits in them. They took it for a road test and after a while on the road test it went back into restrictive performance mode again. They done a smoke rest and found that the near side inlet manifold had split as well. The question is do I replace just the one side or do both inlet manifolds 🤔 and does anyone know how long it takes. Be glad of any help, thanks in advance
