holding back

[ant62]

need some help and advice please, my xtype seems to be holding back at 60mph it starts goes through all gears and seems spot on until i reach 60, i have no warning lights or any signs anythings wrong, until i opened the bonnet i have Oil all over the drivers side inner wing, to hot to investigate at moment, any ideas would be helpful hopefully nothing serious as although its holding back its not going into limp mode. TIA

replaced the air intake pipe with a new silicone one what a difference, worst part was getting the lower pipe clamp tightened i took of the egr that made it easy to get my chunky arm down there

That would definitely cause the lack of air getting directly into the engine and the silicon hose would be much more beneficial and probably cheaper
