hi again, hope you would visit your profile/inbox in next day and see my this message. Im in trouble and a lot of stupid serviceman waste my days. Please help me or show me a way....the problem is O2 post cat sensor's female plugs are doesnot exist on my car. Sound weird maybe, let me explain..I am living some problems about injection time (3rd injector's ms timing is not zero or in average timing range, its raise up to 2ms and later my car engine start to shaking, my fuel consumption is not stable) cause of that want to try montage post cat O2 sensors on my new header's cat. (my car's first owner has removed this 2pcs O2 long sensors from catalitic conv.) and I started to search&find these 2 female plugs/signal cables for connect 2pcs O2 bosch sensors (990mm length cables) but there is no plug no cutted cable etc. Im already using 2pcs pre cat sensors (short cables) I follow their plug signal cables and lead to control unit DME box, I think long O2 sensor cables also must lead to control unit box right? If it is true, then I need buy used female cables and montage it onto right pins of control unit...but how? What I need, a schema, diagram or a drafting? which color cable, which pin etc...I could not find any document, schema or forum topic about it. I know that you are a great person about BMW, please help me, in last 2 days I visit a few serviceman and you really dont want to know their stupid comments! Hope you can show me a way. Best regards, Rifat
