TIRED, just finished some maintenance

Replaced both oxygen sensors. The post cat was super easy. But the pre-cat I had to lower the exhaust, which meant basically removing the cat-back. Once the catalytic converter was free to move I was able to get the 22mm wrench in there with no problems. A couple of hits with the rubber mallet and it was loose. Used the 4wire universal bosch I got off ebay new $55 shipped for both. If you don't hear me complain then they worked. (had 02 sensor fault code) Thanks TTschwing who advised all the wires are color coded to reuse the harness

Replaced 4 coil packs and switched to denso ik22 plugs.

Samco intake hose was a PIA. It was hard to tell whether the hose was properly seated and it's so tight. Have battle scars all up my right arm.

Still need to do the oil change but I'm too tired for today. Working underneath the car with 2 inches from your nose sure makes you tire a lot quicker.

Monday it's into the body shop for the body kit.

"But the pre-cat I had to lower the exhaust"

assuming yours is a 225 (this may work on the 180 too, but I've not confirmed it) you can save some effort next time accessing the pre cat ox sensor. By removing the charge pipe you can reach in from above, behind the cylinder head to remove/replace the sensor. It's a little tricky but you can get a wrench on it, without having to raise the car or remove the exhaust...
