thanks Greg and Klause......background is last fall/winter the problem started. There was/is a code for the ECT not reading so I checked the plug which was corroded and fell apart when I pulled it apart. I opened the plug and removed the female bullet connectors and spiced in new ones and snapped the plug back shut. The ECT is a newer fae. anyway, this weekend I reworked the wires and soldered in new copper 18 ga. stranded wire. I put a zip tie around the plug to keep everything tight. The solder points are in shrink tubing and then I electrical taped over that just to make double sure nothing was shorting. They say polarity doesn't matter, but I found that the yellow/gray goes to position 1 and brown gray to 2. Position 1 is by the angle part of the plug. Went to the doctor and back this morning (about 40 miles) and no problems. Another thing Im wondering about is when my brother jumped me last winter I reversed the jumper just for a second....this can be really bad....maybe I did something to the new sensor. When the needle drops it just goes without warning and stays as if it has no power. Dont want to drive like this much longer in the summer.....I cleared codes again...will check this weekend. I asked FCP to list battery terminal bolts and nuts.....mine got stripped from all the screwing around this weekend. They said they would have on the site by this afternoon under battery....about 5 bucks for the bolts and 3 bucks for the nuts...just FYI
