I don't even have the softare on my laptop yet, I'm still waiting for DHP to give me forum access.

WHat I don't get it why is it this bad now if it's not the 02 sensor?

I've been top-swapped for a couple months now guys. I've run a 14.5 with 0* KR during the whole run and my fuel trims were 0.0 and -2.3 fromt he first 1/8 to the last respectively.

It's got to be related to that sensor because it hasn't been doing this sinec a couple weeks ago, which was when the car started throwing the P1133 code.


Could a vac leak maybe do this too? I had disconnected my boost gauge ON PURPOSE today lol and just blocked the vac T with a cap.

I occasionally hear kind of a "hiss" coming from the pulley side of the engine, almost sounds like a turbine, a very small one. It's a lot louder when the engine is cold though and as it warms up it will go away.
