I went to replace the 02 sensors in my 325ci with a universal 02 sensors and discovered that they were 5 wire while my universal plugs were 4 wire. Me being retarded i cut my original plug first. so i went on the autozone website and the only universal plug that came up for my car was a 4 wire. long story short i cut, spliced and left one wire open. I cleared the check engine light and started it up. Now the trans is in limp mode, this seems to much of a coincidence to be a separate problem. I order the sensors with a harness and plugs,its going to take a couple of days to get here. I hope that's it. trans was fine last night nothing out of the ordinary. Anybody else have this problem. Id appreciate any input.

Trans in limp will engage if there's something wrong with the o2 sensors, all should be fine when you fit the proper ones.
