Hey I'm just wondering if anyone can tell me if your supposed to get a 1 Volt output reading at the O2 sensor wire coming from the ECU when the ignition switch is on but the engine is cold? I know the FSM says to check it after engine is warm and you have drove for a while but my car is running super lean and I don't want to drive it like it is. I have installed a new single wire O2 and I just installed a 3 wire O2 and I'm still getting a O2 sensor code even after taking off the negative battery

Hi everyone,  things are going well with the car. Summer is near and I am planning on taking a bit of a drive.  The cooling system has been flushed recently, car does not appear to have any overheating problems.  There is one thing though that bothers me.  I have a long steep 1 mile driveway.  Usually by the time I get to the top, temp needle is half way up and #1 cooling fan is on.   i have yet to see the secondary fan cut in.  I check the fan motor and the motor relay and both work perfectly

Does anyone know which BMW rotors Oscar-The-Grouch used on his 12" BBK kit?    

Thought I'd toss this poll up to get some discussion.
