Where is my camshaft position sensor on my 1997 Infiniti q45

What is your question?

My Infiniti q45 just went out , it'll start up but the kill after , I changed my coils cause there was a really bad misfire when in low RPM but that didn't fix the problem , Then I checked my spark plugs but also didn't change my outcome . I connected a scanner and it shorted out the scanner . The check engine light came on a few weeks ago then went away but now came on for about three days , then went off one night , then back on again , but when the car died there was no lights on the dash . The car will die when the AC is on but not when off . I'm at a complete loss here , I've also checked for a hose leak but nothing was leaking . I officially don't know what to do this is my daily comuter and can't afford to buy another car .

What makes this problem better or worse?

Worse when engine already warmed up

How long has your 1997 INFINITI Q45 had this problem?
