Your not, I am the same person on impalassforum lol. Just trying to get as mush info as possible since I haven't gotten anywhere in the past few months. I have cleared the codes with my friends MAC tools scanner at his shop, disconnected the battery for a few hours while working on the car and it still comes back no matter what. The only thing that I have come up with is to keep adding grounds. But thats it. Next post will have a 45 min log (long i know but i watched most of it since im still learning and curious) and it with NEW ecm, wires, KS connector, old/new KS and wiring. I have new KS to install and I am just going to defect the ones I have now. Maybe I got bad sensors? I changed one and got nothing, code still there.
