So, use the plug from the sensor in the DP?

Pull a valvecover, pull a rocker and put a dial indicator in the end of the pushrod and read the cam lobe lift and compare to know stats for stock cam/aftermarket cam is the easiest. No need to pull timing cover.
I would start with making sure your coils are cleaned and wires are good and all the wiring that should be plugged in for your car is most importantly the Bank1 O2 sensor that is in upper turbo downpipe.
I reccomend getting rid of the old o2 sensor in the stock location in the rear manifold and putting a bung plug in it's place... it seems to have confused you and others more than a couple times LOL

Turbo setup does NOT use the stock Bank 1 O2 sensor location.
It is moved to the upper downpipe, that is where the Bank 1 O2 pigtail from the wire harness needs to be plugged in.
Disregard the O2 sensor that is in the rear manifold and pull it out of there and plug it up so it does not confuse you and other supercharged guys anymore!

This plug comes from the o2 sensor in the rear manifold. It was not plugged in. I unplugged the sensor in the DP, and plugged in the one in the rear manifold.

Maybe I was told it was deleted, and it wasn't?

Can coils work intermittently?

WHY?
That plug needs to go to the O2 sensor in your upper down pipe.
Like I said, forget that O2 sensor in the rear manifold is even there PULL IT OUT!

You unplugging the 02 sensor in the DP was responsible for the last two codes you got and possibly the missfire code aswell.
Not sure what made you go back to plugging the o2 pigtail back into the rear manifold location, we've been over that more than a few times now. Pull the damn 02 sensor from that rear manifold and plug it with a bung hole plug before it confuses you again.
you're confusing yourself and making problems , if your not comfortable with where things are routed yet take pics before you start unhooking wiring so stuff goes back where it's supposed to.

The codes came BEFORE I changed the plugs. I'm plugging back in the o2 sensor on the down pipe and removing the one in the manifold. I can buy a plug to close the hole at my local OReillys.

I'm going to clean up the coil paks and see if that helps. I found spider eggs under one of them.........EWEWWWWWWW!

And quit YELLING at me........

Maybe I have a bad o2 sensor? DAMIT!

Well ya got two there and one is just plugging a hole...so maybe one is good

I'm not going to try to remove the one in the manifold.......it's to friggin tight in there to get any kind of wrench on it........makes a nice plug too.........

So, before my son left for his girlfriend's, I took another code reading. No CE light, just told the scangauge (I love that thing) to read the codes.......



Stay tuned for a lovely video featuring this gauge reading misfires.......

Looking at ebay prices on new coils.....I'm thinking about giving a set a try......
