Hi everyone I am new to this forum and I am after abit of help/advice. I am 18 and I have a fabia 1.9tdi pd 100bhp which has a custom remap to around 135bhp, just recently my car has developed a problem, which is high idle speep around (1000 -1200) rpm and over revs when releasing accelerator, for example if I accelerate to 2500 rpm when I release the accelerator the rpm goes to nearly 3000 rpm, there is no loss in power or anything the only other thing I have noticed is a oil leak which appears to be coming from around the intercooler area as it's dripping from the offside front wing at the bottom, if anyone has any advice or experienced this problem before I would be very grateful for your help, thank you very much,

Zak

Btw it is a 52plate with 146,000 miles and a full service history
