Can you change that out or is it built in the plenum

Fuel pump?

@@hifiman4562 i am thinking fuel pump or maybe timing jumped a tooth when i was pushing the truck hard when catalist were plugged which was causing so much back pressure it was pushing oil out of every seal and really holding the engine back so much causing jump in time. OR new plugs are so fouled because i replaced plugs first not knowing at the time catalist were plugged which in turn was causing so much back pressure fouled the plugs badly and now thats my issue. Im gonna change plugs again and drive it and go get the fuel pressure checked and go from there. Before all this the truck never used any oil even with such high mileage.

@@zash008 Hi did you found the problem ?

@@ericnazario8350 truck never again had power under a much load (accelerating above 50mph or going uphill). Although it ran smooth as brand new after I replaced all the parts I mentioned. I concluded after all I did that It likely was the torque converter. I decided to sell it instead of spending the cash on replacing torque converter and risking finding out that the torque converter may still not be the issue. I informed the buyer of everything I replaced while trying to fix it. He kept the truck for a month and sold it. It appears he also could not fix it. I bought a 2018 Ram 4x4 5.7L Hemi. The Ram has unbelievably more power than the Nissan Frontier and also I am getting over 20mpg!

Check your evap canister, fuel lines, purge valves etc

Qatari Man it's at the beginning from the air filter

Yep, that's why the reason I replaced it

@@RescueMoversDFW did replacing the intake solve the problem or you had to change the throttle body too???

bmx biker gracias 😎😎

new plenum if you have never changed it before

shamando tal vez sean los catalizadores o checa primero con agua y jabon alguna fuga

Daniel Rescue Movers tenía una fuga de emisión en la linea de escape del Banco 2 ,..puse todos los empaque nuevos , aveces por una junta que este mala pueda que te de un código de p042o o p0430...pero a ver que tal ,ya borre los códigos y ando en la prueba de manejo me vine a Los Angeles. son como una 30 millas a ver si no prende la luz...

shamando muy bien , debes correrla al menos 70 millas en carretera

Daniel Rescue Movers antes de cambiar el intake manifold de tu frontier, que síntomas tenía es decir algun código, cascabeleo, o se aceleraba sola, pregunto por que por la parte donde está el cuerpo de aceleración de mi camioneta se oye como una manguera suelta pero no veo nada fuera de lo común

lo cambie porque se escuchaba un ruidillo en el cuerpo de aceleracion cuando acelerabas . pero es normal el ruido como de aire que se escucha . lo que hice con mi frontier es que se aceleraba mucho mas de lo normal y reprograme el cuerpo de aceleracion y con esto quedo chida mi troca

Yes it had a vacuum leak and also i heard the butterfly (i believe thats the name an internal piece in it) that it was making a noise every time in idle.

Yep

@@RescueMoversDFW oh man, that is what I needed to hear lol. I was freaking out last night. Thought I damaged the gasket or kinked a hose or something. Barely ran, then after some idle time and driving around a bit it seems back to normal.

Nope , never found one . It sounds like there's some but never found it

@@RescueMoversDFW yea i cant solve my p0420 code.. everything new but the cats.. truck does not drive like they are clogged

Nope

I did the same steps but the manifold wasn’t even shaking! Anyway it was past 2 am and I was tired so I’ll see tomorrow.

just be patient

Joshua Figueroa wao, I'm sorry bro to hear that. I don't really know but there should be a video to help you how to do it.

Hope you wernt using impact driver like this idot great way of stripping threads on aluminum heads

Dang! I feel so sorry for you. I hope i never do that!

I broke three coming out. Used a drill bit then a left threaded drill bit and that got em out. Didn't even need to use the bolt extractors.
