Mmmmkay.... I altered the CO screw setting in either direction. No valve action. Disconnecting the sensor would revert to default ratio. No valve action. shorting the WOT switch would revert to default ratio. No valve action. Just applied AA battery to sensor lead, no valve action. I already posted my "Holy Grail" schtick. Again, I'm back to a "missing ground". Missing because: 1) I have not yet found the proper ground wire for the valve and it's open somewhere. or 2) Because the module is faulty. --- In DMCForum@xxxxxxxxxxxxxxx, "Dave Stragand" <dave.stragand@xxxx> wrote: > Rich, > > Then you need to come up with tests to try out each hypothesis.
