Ok so my IS350 I's getting like 3.6mpg right now I do mostly in town driving I live in a pretty small town lol no posted speed I's hire them 35 unless you get on the highway it gos up to 11mpg but then drops on high way it gets like 30 untell I slow down. Abd my cars idyll will like drop to 0 then go to 1 but if I unplug the ETI and plug it back in then it go's back to normal help somone

 

omg that was painful to read, I'm going to guess ESL???

anyways, take a video of you driving so we can see what your doing. It sounds like your flooring it to 35mph everywhere u go. I cant even imagine how its physically possible you'd only be getting 3.6mpg. It's prob a display error

 

thats crazy! you driving like a bat outta hell?

 

whoa, i so cannot understand the OP's post. 3.6 mpg what?

 

Sounds like a problem.....that I can't understand.

 

^^ I think you both need some glasses because I understood everything he said.

OP, are you getting these readings from the "TANK AVG" section of the HUD display? Also is this after refueling? Because I've gotten the same on really short trips after refueling.

If you can post some pictures and if possible a video. These cars report actual MPG's after traveling several miles. The first miles will be off because it hasn't accumulated an average MPG.

 

What's unplugging ETI?

If you are idling, the instant MPG should be 0. Not sure what you are trying to say, like everyone else.

But yeah... want to retype that whole message?

 

lets just assume its normal, next

 

i think the OP is reading the display screen that tells you your instant MPG at the time. the one with the bar. because theres no way your mpg can fluctuate that much from 3.6 to 30 then back to 0

OP, you need to change the display screen to avg mpg

 

Is English still a required subject in school these days?

 

Ok so my Tank AVG I's reading 3.6 and not after refueling on high way it's gets around 30 then after being in town for about 1hour I starting around 9mpg and not driving fast. I think my idling problem has to do with my intake it's a cold Air AEM ETI (electronically tuned intake) and sorry guys I'm a horrible speller even with a iPhone Lol

 

And sometimes my car spells like gas but nothing in leaking I'v done the fuel rail recall valve spring cam gears and brake peddle

 

i hardly comprende but i chuckled when i saw 3.5 mpg

 

At this rate Maybe kids in the USA need to pass the TOEFL too before going to college

 

So you're saying your city MPG is 3.6 and your highway MPG is 30?? Either you drive crazy around town or you have problems. I'm not sure how your average drops from 30 to 9 so quickly either, if you have significant mileage on your tank of gas, to go from 30mpg to 9mpg is hard to do ... Maybe a fuel leak somewhere since you said you smell gasoline? Not sure how you'd manage 30mpg with a fuel leak though haha.

Another idea: Switch back to your stock intake and see if that corrects anything.
