Ok so I've been driving my maxima around for about 2 months with what I though was a knock sensor problem because the self diagnose was showing that code. I got a new one and went to put it in but noticed how much of a bas*ard the job was, so I figured I'd wait for warmer weather. Since then I have replaced the cap and rotor, checked the maf sensor, temp sensor and I knew the plugs had been changed and the wires appeared to be new. yesterday I was picking through the engine bay and suddenly noticed a ticking noise every time the engine's idle would dip slightly, this was besides the tick from the broken and warped exhaust manafold :-(. For weeks I had been paging though countless threads and getting a little worried espically the ones about bad compression. I looked closely and sure enough there was a bright spark arcing from the wire to the valve cover. This wire also happened to be right above where the knock sensor enters the engine. I bought some wires and tossed them on, took a drive and my car is back to normal! Aparently the loss of spark was throwing off the knock sensor, and tripping a code on the ecu. This completely fixed the below 3000 rpm loss of power. so I guess I figured I'd give you guys a good laugh and tell everone to check those wires carefully!!!

Thanks for the info. It's always good to see someone solve a problem. My knock sensor is going off too and it is a new one. Maybe I need to check my coil packs and connections. Good catch though.

did you notice any top end trouble, like as if it didn't want to rev all of the way very smoothly?
