ive been having a lil situation on gas milage, i got this car last year and was running normal and all of a suddon i started burning a grip of gas!!
i so far changed the Spark Plugs(NGK), Fuel Filter, Cap and Rotor and PCV valve but those foos gave me the one that goes on the B20 so i had to cut that extra piece since i have a D16Y8... im waiting on my Spark Plug Wires(NGK)
but dont know if that'll make a difference?? my fuel pressure regulater is set at 41psi but gunna change it to 45psi...
you guys know what else i can do???????
i need help ive been waisting tooooo much money on gas and have none left for other mods....
THANKS IN ADVANCE!!!!!!!!

Gas mileage is affected largely by drivers habits'. The more agressive and faster you drive, the more gas you use up. Also, run the correct oil (on your cap), make sure you have a good and functioning MAP sensor, clean and working O2 sensor, clean fuel filter, and clean injectors. Those, aside from driving habits, also define a large amount in gas milage.

MDM

even if i dont smell any gas????

MDM

i cant quote here at work but to -97Ej6mike - what do i claen the o2 sensor with???????
.. i got a new filter and use Lucas for the injectors!

MDM

lurke artist... yea that might be the problem... should i get any o2 sensor? what do u recomend??

yoffer

Any CEL's? I would agree that you o2 sensor is bad. But i would go ahead and replace both of them. I think they are about 100 bucks apiece from Advance.

MDM

nah no CELs after i got the radiator fan switch.. CELs would turn on every other weak because i placed a wire instead of the new sensor but thats gone!
one o2 is in the header and the other one??? after catalic???

EE_Chris

Why do you have a fuel pressure regulator?

MDM

because a came up with one and it looks nice..lol..
ima turbo that sucker after summer so i can remove the a/c.. why is there a problem with the fpr??

Brake cleaner can clean the O2 sensor, but your better off just replacing it if your gas mileage is that bad. Also, check your MAP sensor, make sure its plugged in correctly, and functioning.

Its good to have an FPR if your planning on boosting, and plan on getting a good tune, but tampering with it on a basically stock motor can certainly deduce your gas mileage if you dont know what you are doing. Leave that stuff to the tuners at the dyno shop.

crazyguy

yeah check your o2 sensor.

MDM

will do ima clean it meanwhile i get a new one check the map sensor but if its bad how do i know??

yoffer

your second o2 sensor would be after the cat coverter.

EE_Chris

Do you have a lot of other mods installed?

Make sure its plugged in, and that you arent getting any Check Engine Lights. If its the stock MAP sensor, and the motor has over 70k miles on it, id look into replacing it, that made a difference when i did it. Their not too expensive. THe unit itself has a tiny nipple hole that is used to detect air flow, in turn, letting the ECU know what amount of fuel to put in. It also helps the idle. Now to check it, make sure the tiny nipple (when the unit is removed) isnt cloged with dust/crud/debris, that would certainly affect gasmileage. It can be cleaned out using a pinch of brake cleaner and a needle or other thin object to free out any debris blocking its tiny air hole. The likelyhood of it being clogged is slim unless you have a vaccuum leak or bad airfilter, or basically any other way foreign objects would make their way to the manifold.

not really i got the fpr and gauge, vafc, boost gauge and a/f gauge since i was boosting but didnt fit cause of the a/c condensor but will remove it after summer since its 116 degrees F over here, intake, headers, grounding kit thats it pretty much stock and slow!!

MDM

97Ej6mike
yea its stock and yea it has waaaay more the 70k miles so ima check that and see what i could do since i dont want to spend a lot of money in that SOHC and use it towards my LSVTEC build but i guess if i want it to run good gas milage im gunna have to waste money so ima do it!!!

MDM

crazy guy...
thanks

MDM

Actually thanks to all

Agent_EM1

So your not gonna change your O2 sensor? i've see nthe change work wonders

MDM

sir agent.. i am gunna change it thats prolly a must on my list! =]
