yeah something is definitely wrong. the evo isnt known for its gas mileage by any means, but you should be getting AT LEAST 200 a tank, even with some pretty aggressive driving.

 

how the clutch feel i got HORRiBLE mpg when my clutch went i mean HORRIBLE..lol

 

It feels ok, i mean it lets off right at the top. Is it sup to feel that way? its stock btw

 

when you hit boost does the car still feel like its pulling good? WHen mine went i could notice the difference. Thats he only real difference i felt really until it was really gone then i would just have trouble getting up to speed lol

i got like 80-120mpg per full tank when my clutch was slipping

 

I get 270 regular, and 340 on the extreme high side. im running cams, full exhaust, intake, and tune. somthing is up on your end.

 

lol ...atleast 2 pages of useless "i get 230+ regular" ...he doesn't care what you average. He's looking for ideas. Lets jump in and post what day of the week it is. Saturday.

 

that made me laugh... anyways tanman i honestly think it maybe your clutch because if you say your completely stock, not on boost too much, and drive normally you should get more then 100, alot more. I had the same experience completely stock, and bad gas milage= bad clutch. but i am no means a professional, just my .02 GL man

 

ya but if he is driving it like a ***** cat like he said he was, clutch isnt sliping. my guess is he bought a car with modifications at some point, put back to stock and tune was left in it, so its fat as hell.

as far as the mileage quotes I made earlier were for reference clown, not trying to not be helpful, just making a point.

when you bag it are you looking like a diesel cummings with all the black smoke?

 

i guess that could be it, but i dont think the tune with stock parts is gonna drag him down to 100mpg.. i had the same problem my clutch was going and i drove it pretty normal not boost, and i would get horrible gas milage, added along to that terrible gas mileage my car wouldnt pull strong like it used to before my clutch went in boost, so i have stated that it could be his clutch, not sure though.

 

lol like everyone says you know what your getting before you bought the car. i didnt buy mine to save gas and thats why i dont complain when i average 13mpg...

 

If his o2 sensor was bad wouldn't he be throwing a code for it? Have you replaced your spark plugs? How many miles are on the car? Sorry if these topics have been covered but I was tired of reading about everyone's gas mileage on this post.

 

I'd say try and get your ECU flashed either back to stock or a tune. Are your injectors stock? Fuel Pump?

I did have an EGR out for over a year on my IX and I still had decent MPG soooo.... Clutch causing bad MPG? I don't think so either....

 

any updates ????? just get it flashed and let us know ... tooo many posts on this and nothing.... if the clutch is slipping get it fixed and blah blah blah

 

I am happy as well, I get great gas mileage when im not at WOT.

 

Couldnt be a bad clutch, RMPs would still climb but the car wouldnt go anywhere if it was a bad clutch and the car doesnt do that, the car just goes and then just falls flat on it face when i go WOT. I just bough some new plugs but i have not put them in yet because im in new york untill monday and no it doesnt smoke like a diesel cummings with all the black smoke. I could be a bad MAF or plugs or o2. Here are some pics of the MAF plug in that i found very interasting, look at this ****!! The clip that the main wire hooks up to is missing and the main wire clip was just hangging on there, wtf? car still runs fine untill i go wot? it will run fine at 0 to 90% throttle but if i go 100% or past 15lbs of boost it falls flat on its face
