Well I am having problems with the car at about 1500 to 2200 rpm. It is caused by the pro m maf and pro m says it could possible be the pcv valve and was wondering if anyone had just plugged the hole in the intake and then put a filter on the valve cover? Please help this is pissing me off because I have lost low end with the stock back in.
