yea I built that 555 o2 simulator, but I dont know if I trust it on my car. If the new sensor doesnt work, how the hell did I fuck my car up?????
I just bought an 02 simulator for $30 off o2simulator.com, i'm going to put it on an oscilloscope in school just to see what the signal looks like, to bad I cant take one home to see what the fuck is going on with my car
I might try that step off thing too we'll see
