so ive been having really bad gas mileage lately and its not my driving style cause ive been babying it everywhere and i dont have any fuel leaks. and i have a skunk 2 IM if that helps at all and then i have 2 more questions one is what should my fuel pressure be set at with vaccume hose on and second on the TB there is vaccume port thingy right next to the idler screw should ne thing be hooked up to it or capped off?
thanks in advance

 

anyone?

it should be capped if I'm not mistaken.

Honestly, I don't think you should even be getting an NSX. You're 17 years old. You just got a 32 over speeding ticket in the gsr I sold you. You will kill yourself in an NSX.

You haven't had money to do anything to the gsr yet, so how do you expect to afford wheels for an NSX?

Get wheels for the teggy first.

 

Check your tire pressure

 

how would my tire pressure cause me to have bad gas mileage? but i did check the pressure a few days ago and its where its supposed to be. when i say bad gas mileage i dont mean like a few mpg less im talking like i have to go back and forth between school and tahts it and i can use up like a full notch of gas doing that and it takes only like 10min to get to school and ive been babying it lately so i have no idea whats up with it. it could just be a fuel leak that i dont know about.

And tony chill buddy the nsx thing was sarcasim

 

When was the last time you did a full tuneup??? That would be a good place to start.

If you are running too rich that will defentialy hurt milage, also if the 02 sensors is going bad that can hurt also.

Ditto.

 

well its not running rich i think on friday im gonna put it up on a lift to double check that there are no fuel leaks. oh also something just came to mind could the possibly be affecting ne thing the drivers side axle is going bad like where it connects in the metal coupling thingy lol is lossing and it like clicks around when i take turns could this be doing ne thing funky to mess with fuel mileage? also could it be the gauge is fucked up cause its got a jdm cluster in there .
thanks.

 

well yes, when the axel clicks it is usually directly linked to a loss in fuel...the cluster is fine, worked fine when antek had it. I guess you could test how many mpg your are getting. Fuel pressure should be at like 48, and the vacumn line should be capped when you are running the car, but uncapped when you adjust you fuel pressure

Hahaha Matt! I seriously LOL'd (yes, el-oh-elled) at that one!

 

well i wish i had worded that differently obviously a clicking noise is not related to fuel consumption im asking could a messed up axle cause gas mileage to go down in any way, oh and also i think i read somewhere that the s2 im can cause gas mileage to go down as well does anyone know if its a drastic decrease or what.... anymore ppl with real advice thanks.

 

get a new axel from advanced, there are like 3$ The intake manifold really isnt doing anything except allowing more air flow (due to the larger runners), so it shouldnt be a very large difference on mpg.

 

im short on cash right now so getting a new axle is out of the question for a bit but i know what the intake manifold is doing the thing i was talking bout manifold wise is that i read somewhere the manifolds dont always match the ports right so i figured that might be doing something but im not compleatly sure.

eww, I forgot about tire pressure.. this can have a noticable impact. also you can get some narrower tires. When I put my 205's on the EF I lost like 30 miles per tank.

 

hmm i didnt know tire size could effect that ill have to look into that more, also i dont know how i didnt think of this b4 but could a bad fuel filter and funked up air filter be causing really shitty mileage?

Changing your fuel filter would be part of a full tune-up. Your air filter is fine.

 

ill have to check out my fuel filter. but i dunno bout the air filter dude its lookin pretty bad, i might just get a new filter see if it helps ne there not to expensive either way.
