I have a B16a installed and I think my knock sensor is bad. I dont know because it must have been bad when motor was installed. Vtec does not hit hard at all so i dont know if it is even engaging. I here a sound change at about 6000 rpms but it doesmt pull hard at all. Any way I got a skunk2 manifold for 175 brand new and i want to put it on when i am fighting with knock sensor. Is the install of the manifold any different on a b16 then a gsr. I cant find any info on b16 installs but alot on gsr installs. It is going to be for a 98 hatch so i want it OBD2a compliant. Thanks
