Car bogs when going into Closed Loop
After installing my Procharger, along with SVO 42 lb/hr injectors and TR6 plugs, the car bogs really, really badly once it's in Closed Loop (after 5 mins or so of warming up).
Once it gets into closed loop it also sets an SES light, P0300 Multiple Random Misfires. My LTrims while cruising are -1.6% on one bank and +22% on the other.
I have basically determined there aren't any exhaust leaks.
What could be going on here???

Re: Car bogs when going into Closed Loop
Bad O2 sensor is what it looks like.
If the car runs fine (good throttle response etc...) while it is in open loop, then you can basically rule out a vacuum leak.
The P0300 code is being set from the cam.
Change out the oxygen sensor and see if your problem goes away.
Good Luck

Re: Car bogs when going into Closed Loop
I do have a cam. a TR224, but I already had (using Edit) reduced the sensitivity of the misfire detector and until I put the blower on, I was not getting that P0300 code since I tuned it.
I did adjust the IFR for the bigger injectors.
I will swap the O2 sensor and see if the +22% moves with it. I hope you're right!!!
Any other ideas though?
