Hi Bruce. Well it's taken me days to get back to you. Firstly, thanks for this & I think one other reply you sent me. I appreciate them. I've been ruminating on this info you sent, mixing it w/the symptoms the car was having (slacking engine speed while driving, accelerating, anytime, very intermittent). The intermittent problem, when combined w/your description of the wiring layout makes me wonder if the problem could be a glitchy relay, either lambda or fuel pump. Granted, the pump relay should stop the car if it's fritzing, but the slacking off of the engine was more like a fuel problem than a tranny problem. As soon as the gas is kicked, the engine revs up, the gears kick down & the brick moves. Bad tranny should just sit there & whine at me w/no real response to more gas. So, my new question is, have you ever heard of a glitchy relay, named above, that would do a partial cut out of the fuel supply? Obviously, if the control press. reg. isn't vital to the running of the car after warmup, the grounded blue wire may not be that critical, but maybe the circuit it's part of is shorting intermittently causing my problem? If this sounds like stuff from outer space, just say so. If there's no way in heaven or hell that one of the associated relays could cause this partial part-time failure, I can handle it. I haven't had time to get back under the hood, but am planning to at least pull the fuel pump relay, the lambda relay & the aux. air wiring to see if the grounding on the blue wire goes away. Thanks for your time & input.
