Right I thought I'd resloved this with new ECU and Remap but NO please can anyone offer some advice. Car is a Version 5 Type R.

 

maf ???

 

front of your engine to the left of the alternator there is a black plug that tends to slide off easily, not normally clipped in place..

when that comes out , it gives u a high idle.. i.e. 2.5k rpm is what it did on mine, slide it back on, all resolved.



edit: not sure if classic has this plug tho.. can be seen in pic above..

 

eggy790 thanks for the response its a classic wheres the plug on yours?

 

i havnt seen a classic engine bay for a while, but if you see below i have circled where it is in green on newages.
