2004 325ci unversal o2 sensor 5 wire 4 wire
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.
