Hi, 3 week before I had problem in XF(2009) poor acceleration and miss firing in morning time. I discovered that AIR INTAKE TUBE (with small plastic box) corner is broken which seems to be poor quality plastic. Any way I checked price with Premier motors and then came to know one supplier in sharjah who is sourcing directly from UK at lesser price. Even suggested work shop in Dubai who can replace this part at very competitive price. (in fact it was a replacement not repair). Now car is running very well. Let us share experiences . Bye
