cold air has more resistance than hot air...so has it been cold there recently?

If just 'cold air' is causing a 10 MPG drop, I'll move to Death Valley. NONE of my other cars, through sub-zero(-20 at times) temps have had this mileage drop. I do understand that cold air creates more drag, but thats like saying that my mileage drop is caused by me not waxing my car often enough (a dirty car creates drag too!).

thats a 33 percent drop. it should have showed up on the exhaust test unless the catalitic converter is working over time to clear it.. check your plugs and see if they are black fromthe the engine running rich..

x_rayted711

I was thinking that too...Maybe change them out. Can you recommend a good plug? I also read somewhere about indexing them? I wonder how many 'little' things are affecting this problem?

I started a new thread on here to see if someone can post up their emissions test results and I can compare them, but no takers yet!

as a tech for toyota i get these ? all the time seams like you have been put on the right track first thing you should all ways do is try a diferent gas the gas is so bad that even gas stations by the cheapest no matter what the sign says and please dont play w/ma you will mess it up it is very ez the wire is very very small and and will be damaged even by an air blower trust me

I use HESS petrol and overfill my gastank about 3 clicks.

I have tried 7 stations in my area now...and two in another town south of me.

I have been driving 6 miles each way to work and home...an ocasional stint on the freeway here and there, but I almost always end up staying beteen 30-40 MPH.

Should I get on the freeway and just DRIVE and DRIVE 70-80-90 MPH for a couple hours and then refill it and see if the ECU changed?

MASTERTECH

all you have to do is pull the ei use for about 3 min. and put it ack in that will reset you ecu and you can try starting rom there
iget @38-40 but i drive 45 miles to work on the free way one way

kill the caps and fix you "f" key , and your "b" key

resetting the ecu will only help if theyre been using bad driving characteristics and it learned itself in that manner.

x_rayted711

I already pulled the fuse....# 12. No difference...

x_rayted711

Go ahead hotbox...I know it's coming!!!





Tell me I'm cheap and I should get rid of my new car if I can't afford it....All because I'm concerned about the MPG....Go ahead...I'm ready for it.

hotbox05

if u were complaining about 32+ mpg then i'ds say that. but yer getting what 25?

what are your driving habits?
does your car feel sluggish?
is it bogging?
is the brake stuck part way on?
do you have huge wheels?
do you have a leadfoot?

x_rayted711

If you read the whole post you would know more of whats going on as far as driving habits, wheel size, type of gas, where I get gas, etc.

And to let you know, I'm getting a consistant 22MPG...GO ME!!!

I understand where you are coming from with that other post about the 32 MPG, but to get on him like that? I think someone needs a hug...

x_rayted711

BTW...who's following who?

hotbox05

you followed me so i'm following u.

i don't like hugs.

i've read this thread a long time ago. and with as slow as scionlife and myspace have been lately i'm not down with re-reading things unless I have to .

x_rayted711

And you don't have to...You know my situation. Bad Mileage. Anyway, have any ideas to help?

hotbox05

does your car feel sluggish?
is it bogging?
is the parking brake stuck part way on?
do you have a subconscious leadfoot?
did your car do a lot of idling during 'break in"

x_rayted711

Sluggish-No

Bogging-Yes..at the line if I nail it, it just bogs for a couple seconds. It WILL NOT spin the tires even with the Trac off. Also, when slowing for traffic or a light and then getting back into the gas, it bogs and/or takes forever to downshift (like from OD to 3rd or 3rd to 2nd).

Parking brake dragging-No

Subconsious Leadfoot-No. I continuously have my eye on the Speedo and keep it adjusted to whatever the limit is.

a lot of idling- Not during break-in, but I DID lock the keys in it with it running for an hour and a half (damn remote start). It had already gone over a few thousand miles at that point. And also, I didn't suffer the mileage drop till 4-5 months later (Oct.)

hotbox05

that bogging is quite worrying. sounds like an air leak/maf problem. and or your transmission control. auto right ?

x_rayted711

Shouldn't those show up on the emissions test or check engine light?
