Multiple emission related codes: p0037, p0421, and p0300.
From a recent coil pack total failure coupled with 190k miles, I'm reasonably certain the front cat needs to be replaced now and I'll get moving on that. And at 190k, I think I'll go ahead and change the O2 sensors.
Question is how do you know if the rear cat needs replacing? It doesn't seem to be monitored by anything, so how do you know?
