You have all the classic signs of a bad CPS, but CPS's usually throw codes if the symptoms are that bad. Have you had a SES light at all?

Have you fault codes check, see whats up.

You should really pull the codes. There are two CPS for each bank, an exhaust and intake, 4 total.

So the guessing game is not a good idea..

Sounds like you have it nailed down. Hope the CPS solves your issues.

There are 4: bank 1+2 exhaust, then bank 1+2 intake

Since the car will run, just poorly, with bad CPS's i'd say not replaicng them isn't such a risk... Not sure how much 'labor overlap' there is- if it is one hour of overlap, then it does make sense to replace.

I did my own and...

I can tell you that on the driver side bank, since you are in there you might as well do both. I had to remove two coolant lines in order to access the sensors so it just made sense to me to do both.

The passenger side was much easier, just remove the airbox as described in the tricks and tips and you can fit a hand with tool in that space.

I kind of subscribe to that old light bulb analogy.. the one where as soon as the left marker light goes out and you fix it, its right back to the parts store because the right one got jealous and burned out.

And yes a bled the cooling sytem after I was done.

Those sensors weere about $100 a piece,or were you taking it to the $tealer?
