Went back and double checked to be sure, still not showing anything above .01 ACV. Found an OEM CPS and ordered, will be here this week. I also have an exhaust leak that's been slowly getting worse, haven't found the location but almost certain its a cracked manifold. I recently picked up an HO exhaust manifold with the expansion pipes for cheap, so this may work out by being able to kill two projects with one tear down and much better access to the CPS.
