Help! I have a 940 thats driving me nuts. I have read all of the threads. The only code showing up is no signal from an o2 sensor but have had it running fine. I have replaced crank postioning sensor because it tested bad. I have cleaned every sensor and connecting switch there is. I can get car going but it takes lots of work, I thought it was flooding but I ended up finding out my spark is weak. I tried jumping a wire from the battery directly to the coil and it started right up after burning some of the excess gas from cranking. It runs great once it starts, could this be the ignition? Thanks much Craig
