All: I have a 2002 SC which also exhibits the 'NO POWER" symtoms after warmed up. I plumbed in a boost vac gauge and confirmed that upon startup, I get 7 PSI easy and after warmup only 2...the bypass is obviously on. I want to change the knock sensor and was looking for anyone who may have swapped in a maxima one with the harness to chime in and recommend a good place to mount the new sensor. Thanks to all in advance
