hey guys, I'm stuck and I can't find anything that answers my specific problem. I have a 97 4wd LS and I was having problems with the transmission getting stuck in limp mode. I ran the codes which came up p0141, 146, etc. so I changed the ignition switch and it seemed to fix it, for a while. About three days ago it went back into limp only now it won't come out like it did before. The codes I'm getting now are p0740, p0785, and p1860. I did just replace a couple o2 sensors as well and had it running great for about a week. When i look these up it says it's probably my wiring but where do i start to check that? And I'm not sure if this matters but it has been raining a lot here(Denver) and i hit some good sized puddles that day... Any help would be appreciated, with-out this forum i'd have been broke or crazy already. Definitely been a learning experience though, not a disaster thanks to all of you!!
