New spark plugs and new O2 sensors now installed. The O2 sensor on the passenger side was easy. The one on the driver's side was a bit of a b*tch. I had to buy this removal tool which actually worked really well.
I was hoping to use O2 sensors I had left over from my old E36 325i would work....and they did!!!

The lead is too long, but you just need to zap strap it shorter
The car runs smoother for sure, but it's not as smooth as I was hoping it would be. The old 320i that I had ran sooooo smooth sometimes I had to look at the tachometer just to see if the car was running. Still love this car though.
