driveability...

So this is what happens after installing my new pte 50 trim, fmic, and greddy type S. At idle there is no 02 signal and all the way up to around 4000 rpms there isnt any. but if i shift, between shifts it sends out a signal...and when there is boost, which is very weak, the 02 signal is .88-.90, do i just need a new 02 sensor possibly? Right now i have the bov venting because i couldnt get the stock hose on so i have to get something different to recirculate it. Also, at below boost rpms there is 0 counts of knock and as soon as it boosts it shoots up to 43 counts. The engine seems very gutless right now, i could have the mbc hooked up wrong though. Any input would be helpful...thanks guys

I don't see any supporting Injectors for your 50trim/setup. Your knock can be real knock depending on what your boost level is compared to your safc settings and base fuel pressure.

As far as your O2 readings, if you dont get at least .15V-.25V at idle, its highly possible the o2 is shot. Replace it if you haven't already.

Probably your knock sensor going out. I know today with my car, I saw knock shoot up to 43 counts with partial throttle. This has never happened before. I'm sure it's my knock sensor going out since when I felt the sensor from the back of the block, I felt some goop seeping out. I'm assuming the best way to remove it is to remove the intake manifold bracket? I'll hit it from underneath the car since that's the easiest for me.
