100% agree but I don't think anyone will know what you are talking about if you call it an "intake pipe with less restrictions in it" or a IPWLRII. Say "cold air intake" or CAI and everyone knows what you are talking about. "CAI" is still a misnomer for anything that s...

RE "K&N cold air intake" How is the air in the engine bay colder than the air outside of the engine bay??? Lol, +1. It isn't, and the IAT will prove it for those who bother to look. When there is any improvement from an "in the box" CAI, it's almost always from removing rest...

Sometimes the front cats fall apart and the debris clogs the rear, but aside from that, rear cats don't cause many problems. The fronts do the bulk of the work converting CO and breaking down HC, so the rears are usually rhodium types simply there to break down NOx which the fronts are less efficien...

You can confirm the presence of a vacuum leak with a scan, but it won't help you find it if there is one. Warm up the engine and stream the STFT for both banks. If neither is high (or only one bank) then the problem probably isn't a leak, but if both read higher than about +10% then proceed. Raise t...

The FSM steps are likely to send you on a lot of unnecessary tail-chasing. First question, do you own a good scanner? If not, you'll probably need one. Streaming parameters like short term fuel trim (STFT), MAF g/s, and cam timing will prevent you barking up a lot of wrong trees. That said, given th...

There are two separate fuses for the radio, one ignition and one battery. The battery fuse is under the hood. On upper grade radios you'll usually get a "no audio" message if it's blown, but on base and mid grade units, the radio will work but won't remember anything. It's fuse #29 in the ...

Hall sensors on Nissans are largely a guessing game. The ECM's are good at detecting flatlined sensors, but terrible at detecting a sensor that's working half-a$$. So when you get mystery stalling or performance issues with no engine light, they're always a prime suspect along with the MAF sensor.

That sounds very much like a crank sensor that's misbehaving with temperature.

Actually, the biggest cause of "duh" stalls on just about everything Nissan is cam or crank sensors (most often the latter). You can eliminate or implicate the fuel pump very easily by spraying Brakleen or Gumout down the barrel past the air filter. If that starts it then the problem is fu...

According to the FSM the cargo outlet and lower front outlet are battery, not ignition. The upper front and console outlets are ignition. See PWO-4 here:

Good work!

The '19's still had regular fuses located in the IPDM (mounted upside down at the back of the underhood Fuse & Relay Box, which is located in front of the driver's side strut tower). H9 means you must have changed the high beam bulb, low beams are pretty much always H11's if you have halogen hea...

Since the truck will start it means the TCM is alive, on R51's the PNP Relay for the starter is driven by it. If you don't have a lit MIL, it also means the TCM is communicating, because you'd have U1000's all over the place if the TCM was incommunicado. If you had a genuine milkshake and not just p...

Yep. Easy job on an R51.
