SOURCE: i have a 1999 nissan maxima with code P1320

This code is a crapshoot. There are two main things it could be and they are both expensive. There could be wire breakage in the engine harness. There is a thick harness coming out of engine bulkhead on the passenger/right side and it has a slight bend to it. With the engine idling grab that bend and give it a couple of twists and yanks. If the engine stumbles or misses that is the source of your troubles. If not, you more than likely need to replace the coils. Any one of the six coils could be causing the code so I recommend replacing all six at the same time. You could buy one coil for the front bank and one for the rear and swap it between cylinders to see which coil is causing the code. This is time consuming but cheaper.

No - not a knock sensor ( It will not create "no start" condition) - but more than likely -(if not an IAC (AAC) valve ) - it could be a cylinder head temperature sensor - or it could also be an intermittent fuel pump failure or an intermittent ignition failure - However, I'd bet it was a head temp sensor - do you smell fuel when it won't start??

this fault code would indicate you have a large evap system leak.most often sets from a fuel cap not secured.since thats not the case i would bet its the vent control valve on the evap canister sticking open.evap leaks can actually be cheaper to fix if taken to a pro or dealer with bidirectional scan tool and smoke machine to pinpoint leak.the darts get fairly expensive on evap codes.if it turns out to be the valve expect about 250.0 0for diagnosis, the part and the repair. let me know how it turns out.

What is the IACV? And where is the electrical connection to the air mass flow meter at, in a 1995 Nissan Maxima? Also, I need to know where all vacuum lines/hoses are, to be able to replace them all.

IACV= idle air control allows, and controls the amount of air into the intake when the car is at idle..and your MAFS, mass air flow sensor is connected to your air filter. It will be between the air filter and the engine in the breather tube.

I have a PO code 505 on my 2000 Nissan Xterra and want to know what is causing that read out.

Alldata says
IACV-AAC valve. Don't mess around with this issue. If it shorts out it WILL take out the ECU.
Replace it as soon as possible if it's bad. You may have to pay for an Idle Air Relearn as well.

Why does my 1999 Maxima hesitate sometime when I step on the gas. It seems to be getting worse?

Tuned up lately? semms a bad MAF sensor or EGR valve, also a cogged fuel/air filter can cause this or even bad spark plugs can cause this to happen.
