My 95 sc300 is throwing code 21 and what I've found from searching is that it is my o2 sensor. but how do I tell which one is bad? Also the 41 I think is the TPS sensor but what could this be saying? The only thing I can think of is that today I deleted the egr with some plates I made. I have heard that this will not trip any codes but I only drove it about 5 minutes when the code 41 was dispaied. I have done lots of searching on this but It might be that I didn't know what to search for. So if you want to tell me to search please be kind enough to tell me what to search for.

Thanks
