Pulled the plugs this morning and they all look normal. Gapped them down to .035 from .039 while I had them out. Breather covers are leaking again. IAT sensor is clipped in place like it's supposed to be. The only problem I found was the hose had popped off the bottom of the secondary air injection ..... at least that's what I think it is. The big round whirring dervish at the front, drivers side of the engine bay.
The codes, I got a P0158 and P0161 along with the miss fire codes. After erasing the codes the only one that has returned is the rear O2 sensor heater circuit. I'll be ordering an IAT sensor on monday since it's acting strangely and keep an eye on the O2 sensor codes. I took a couple of pictures that I'll post up later, if they came out decent.
