Hi, I posted about this problem a while back and had a few replies but need some more help please. So the issue is still the same. When the car reaches temp the revs go up to 1500 - 2000 and drop down again. And keeps doing it. I have had it plugged into a scanner and the following fault codes came up.
P2279
P0507
P2187
P0100
P0171
I have checked the PCV but can't see any damage to the seal.
I have heard of a BHC (sorry if I got those letter round the wrong way not sure what it was) conversion kit. Is that worth a go? Not sure what else to try.
Any suggestions?
Thanks guys.
