my LPG fairmont (EFI) has the ERG vavle been blocked off? is that good?!
MY dual fuel '86 Fairmont did a head gasket so i fixed that, but in the process i noticed that the ERG valve had been deliberately blocked off (i think) from the manifold. Where i assume there would be a gasket between the ERG and the manifold, there is what looks like a gasket with no holes, so the gases cant re enter the manifold. has it been blocked for a reason? or was it a mistake from the previous owner who might have done the LPG conversion himself.... my car idles fine but seriously lacks midrange power. i thought that the LPG was the reason for that, but i drove my mates which is identical and his is noticeably zippier then mine. is this something i should be concerned about or should i just accept i have a very tired old XF haha
should i clear the valve? or is it blocked off because of some LPG issue?
