Couple Questions - Code 125 & Supercharger Question
Hey guys how's it going. Just got a couple of questions. I have a 99 Solara with TRD supercharger running 4 psi of boost.
1. I just installed a new set of headers w/downpipe, mostly because my manifolds were leaking. After install, I got rid of code 440, but after driving a few minutes I developed code 125 - insufficient coolant temperature for closed loop operation. When installing the headers, we had to extend the wiring harness that goes to the O2 sensor due to hole being drilled in the wrong location. (Bought cheap headers off ebay from tuningpros) Would this be causing this? Is there anything I can do about it?
2. Also, something I've noticed is that when driving If I mat the pedal from a stop, the boost will jump up to 4 psi but then when the transmission goes to shift in to second I lose all my boost for a second while it shifts, then it spikes back up to 4 psi when it completes the shift. I thought it was belt slippage maybe, so I installed a brand new belt but this persists. I am asking if this is normal, and if not how can I fix it?
