OK thats cool, but how can that lead to burning black smoke? Anyway Thanks for all your help I found my problem on the red Supra you have been helping me with the timing belt must have jumped. The belt is in real bad shape but not broken. Cracked and missing teeth. Timing marks are off by quite a bit! Has to be why it died. I will come back to this thread though and hope to learn more about the O2 sensor. I have never replaced one or had to. Thanks, Scott
