Too much gas?

[Haccord21]

I honestly am thinking that somethings going on with my my engine and my gas. Im not sure what it is but my car is using up more gas then my parents trucks. What could be the cause of it burning up too much gas? Would exhaust leak contribute to this at all? Sorry if this is a stupid question.

[eriemoto.]

have you ruled out all of the obvious by doing a full tune-up? what is your approx. MPG? that would help to diagnose the problem, depending on how much MPG you have been getting

[Haccord21]

Ive had the car for a good year and a half i think i can say. I havent done a tune up yet. I was thinking about doin that this summer didnt think it would really affect my gas. And im not sure about my approx. gas mileage. Whats the best way to figure that out?

spark plug
incorrect ignition timing
overheating
o2 sensor
carbon deposits
bad ringland
old oil
vacuum leaks
exhaust leak
horsepower
stupid, idiot tune(like my car was )
beating on your car
incorrect fuel pressure
incorrect tire pressure
incorrect suspension setting(camber, toe, etc.)

i think i covered everything

[sulimed]

also how do you drive the car. like a normal person or...speed racer.

Now heres a list of what i know is ok cause ive changed it:
overheating
old oil
Heres the thing you mentioned that must be a factor in this:
spark plug
incorrect ignition timing
o2 sensor
bad ringland
exhaust leak ( I have this)
stupid, idiot tune(not so sure)
beating on your car
incorrect fuel pressure(I have a fuel pressure regulator, fuel rail but i donno how to adjust it. or what it should be at. When the cars on the Fuel Pressure regulator reads at 2. I believe)
incorrect tire pressure
incorrect suspension setting, lowered on coilovers with no camber kit

when you fill up reset the trip odometer....next time you go to fill up take the miles on the trip odometer and divide it by the gallons you just filled up with

[Haccord21]

Alright. I just filled up today so ill restart the trip odometer. thanks

ok then i'll break it down w/my knowledge, which is limited, still learning myself(oh, shit here i go, watch me now )
spark plug: bad plugs and incorrect gaps can cause misfiring, not enough spark, and hard starting and such

incorrect ignition timing: this is complicated but its basically the cylinders not firing and maximizing the fuel to burn right, so it would burn too early, too late, or not enough, preignition, detonation, etc.

o2 sensor: your ecu reads a signal from this and corrects the timing, fuel, etc. with this being outta wack, it would dump fuel unnessarily(like i had when i was going to daytona). you'd get a CEL for this though

bad ringland: low comp, not enough power, have to push it more to just to get average speed

beating on your car/tune: thats a whole 'nother ballgame

tire pressure/incorrect suspension setting: this can affect mpg ratings due to the car has to push itself to move(i.e.-low pressure, camber hella off, like a bike w/no pressure in its tires), also big ass rims that arent properly inflated also do more harm than good. also you said you didnt have a camber kit, this may add to it, no much but ehhhh.....will kill your tires though if its real low

if its adjustable, there should be a screw or somthing like that on the top to adjust fuel, dont know what stock ratings are but i think its like 40psi. if its stock then check your fuel pump, may be going out.

oh to add to the list BAD GAS and improper servicing

[Haccord21]

"spark plug: bad plugs and incorrect gaps can cause misfiring, not enough spark, and hard starting and such"

Thats a problem that ive had for a while. prety much since i bought it.

"if its stock then check your fuel pump, may be going out."

One of the guys told me that if my cars having a hard time starting that i need to check the fuel pump. Told me to turn the key twice just before it switchs over and you start crankin it. I did it twice and he said if it starts right up after that then your fuel pump is going out. So now you stating this makes me really think my fuel pump is going out.

now for the tune i'm not sure if bracersi ever actualy got a good tune on this car or not. Would it really be worth taking my car to a shop to get it tuned if i really havent done anything to it?

[ceelooboob]

i say you do the full tune up and go from there....
ngk spark plugs and wires
cap and rotor
fuel filter
pcv
airfilter
valve adjustment
bottle of fuel system cleaner
oil change
tranny fluid change
blah blah


and yeah a bad tune could make your car run really rich and just drink gas

[Haccord21]

Ight thanks. Im getting paid on the 5th so ill be able to do most of the tune up. Thanks guys.
