NISSAN MAXIMA TROUBLE CODE

I Have Two Codes And I Can't Find Them P1320 And P0505. I Need Help Trying To Figure Them Out.

My Car Started To Shake For About Two Seconds And Then A P0420 Code Came Up. Would A Bad Catalytic Converter Cause This? Thanks

This Car Has What I Would Disccribe As A Ignition Ping When Enging Is At Operating Temp Under Acelleration Or When Engine Is Under A Load....

I Have This Code For A Af Sensor I Have Already Replaced It However Code Is Still Their.

The Car Cranks But Never Starts And The Radiator Fan Still On With The Switch In On Position.

I Look Up These Codes And They Are System Too Lean On Bank 1 And Bank 2. What Do I Do To Fix These?

I Hooked Up My Vehicle To Live Data And It Doesn't Show Any Of My Cylinders Misfiring. I Replaced The Front Engine Mount Thinking That...

Throttle Control Motor Relay? Location Of The Relay And The Estimate Cost Of The Problem Caused?

What Is This And How To Repair It Myself, Cause My Service Engine Soon Light Is On.

Engine Light Came On Took To Dealer Said It Was Rear Catalytic Converter And Now Engine Is Back On And They Said It Might Be The Front One...
