I'm going to recommend locating the mass airflow sensor. Check the rubber hosing that connects it all together. If there is air going in that the mass airflow sensor doesent read, then the exhaust will show it at the oxygen sensors. The PCM will likely try to compensate for the lean condition by throwing ridiculous amounts of fuel at the mixture but without the Mass airflow sensor, it won't know how much is actually needed. Also check for anything that may connect to the rubber hosing, like elbows, or tubes, or even sensors that fell out. If there is an airleak AFTER the mass airflow sensor, you have air going in that the car cannot read and adjust for.

Please post results.

Sounds like you may have a plugged catalytic converter. Find a shop that can check backpressure in the exhaust. They will have a tool that threads into the O2 sensor bung. They will use a vacuum/pressure gauge to see ho much back pressure there is in the exhaust. Anything more than a couple of PSI and there is a restriction.

SOURCE: poor fuel milage

Check your ECM codes. A code P0328 means your knock sensor has stored a code. Apparently when this code is stored it does not change much on a non-supercharged 3.3L engine but does on a supercharged one.

I'm going to try using the recommended higher octane in my 2003 supercharged 3.3L Frontier and see if the code disappears. If not, I plan to relocate the knock sensor to a more wrench-friendly area.

How do I recharge the air condition on my 2000 nissan frontier?


If it needs to be charged,it has a leak & is poluting
the atmosphere

Therfore it need to be leak tested,system repaired,
a vacuum pump attached & the system vacuumed
dry,then properly recharged

You have no way to add & know what is in there
or being put in

You need A/C Manifold Gauges just to check the system
operation & charge correctly.

Charging may not be the issue at all

Need it diagnosed by a person train in A/C repair

Belts squeal on 1998 Nissian Frontier


Squeal belts usually mean not enough tension. I have had problem with persistance squeling in the past, the problem turn out to be cheap aftermarket belt that keep stretching and wouldn't maintain proper tension, putting brake fluid or any kind of oily liquid on your belt will make it worst not better.

2007 Nissian Frontier trailer lights


There should be a 30 AMP mini blade fuse in the fuse box under the hood that you are probably missing. I assume that since you got the relays with the wiring kit, that you got the kit from a Nissan dealer. If that is true, there should be a fuse in the kit also- in a sealed bag that has the "trailer wiring harness owner's manual" in it.


Hope this is helpful!

You have 2 cats B1 & B2 and it sounds as if the right side (B1) is clogged. If that's the case you will need to replace it with a new one from your Nissan Dealer. While your in there you should check the condition of that right exhaust manifold as they are known to crack and if so replace it while your replacing the cat. Hope this helps.

hi its definatley an air leak if you have replaced the hoses i suggust the next thing you try is see by tighting the carburrettors nuts that hold it to the manifold as these come lose and **** air do the same with the manifold bolts i suspect you will find them loose if not then change the gaskets one at a time with the cheapest first the carburretors then the manifold you may want to go to your car shop and ask for an air leak spray or they may use some other kind of method but basicly you spray it round the carb/manifold and watch to see where the leak is yates210456
