Im thinking all of my codes are from running too rich, but is there a way to tell if I need a new O2 sensor or not? One of the codes states that it *could* be defective in bank 1 sensor 1. Which side is that? I only have front O2s


Anyhow here are the codes. Id like to replace the O2 if it needs replacing asap because I finally found a tuner under $300 and Im getting it tuned Monday morning.

P0133 - Slow response bank 1 sensor 1
P1153 - insufficient switching (most likely not enough oxygen to the sensor)
P0300 - misfire detected (could this be due to an improper A/F ratio? Im rich as HELL)
P0332 - Knock sensor ( Could this also be because my A/F ratio is screwed?)

I got rid of the EGR and I never got it deleted or tuned since...
I guess what Im really asking is how do I know if I need a new O2 sensor and will an A/F tune and deleting the EGR in the computer make my vehicle run correctly again?

You could very well have real problems, but when multiple independent systems are involved, check for bad grounds first. This is just a matter of diagnostics. You could have a ton of problems, or you could have one loose ground wire. If your car is your baby, and you clean it religiously, it is probably corrosion on one of your grounds.
