Code/ stall

[RawBurt]

I've had the p0172 (i think thats it) for awhile now. Bank 1 too rich. I've had the NP turbo kit on my car for a couple hundred miles now. And I recently threw a p0175 (bank 2 too rich). I searched this code and came up with many different possibilities. Also the car likes to stall when coming to a stoplight. Related to the 0175 maybe?

I did check the compression the other day and got no lower then 183 and no higher then 195.

how old are the O2 sensors?

Its p0172, sorry.

I'm more worried about the 0175 though. I just stated that I had the 0172 forever. Both rich codes.

Which o2 sensor would the 175 relate too? The ypipe?

O2 sensors are the up stream sensors ... the cat monitoring sensors are down stream ...

so P0175 is bank 2 ... sensor closest to the engine ...


have you done any data logging to see how the a/f is and whats going on in general to refine your tune?

No data logging yet.
