My new 2010 Yaris seems slow - Toyota Yaris Forums

I PHANT0M I · 01-24-2012, 08:47 PM

It seems slow off the line, reason i say this because my Fiance 2008 Yaris is fast of the line it seems like i have to really push on the pedal to get it going...

Anyone have any ideas what could cause this?
so i can take it to the dealer and see if they can check if there is anything wrong with it
i use 91 octane Fuel if that means anything.
Thank You!

The engine is designed for 89 octane. Using 91 will not:

-Yield significant power gains, if at all
-Get you better fuel economy
-detonate properly (the compression ratio for use of 91 is different then what the 1nz-fe is made for)

Is your car auto or manual?

The auto Yaris is quite possibly the slowest production vehicle in the states

In terms of 1/4 mile numbers maybe, but on the road there are a lot of vehicles that are slower off the line. Vibe/Matrix for one.
Yaris is not that bad.

even coming off a V6 I find Yaris pretty good in the city. it does run out of steam on the highway though.

Oh man, maybe that explains the marginal gas mileage I've been getting since I bought mine last year. I had a coupon for $0.50 off per gallon, so I "splurged" and filled it up with 89. Goes like stink in first, gets up to highway speeds with the quickness.

Maybe the trottle body needs a cleaning . Try a few tanks with Techron and 93 octane from Shell or other major gas company . If you do , let us know if any improvement .

Kioshi · 01-25-2012, 12:48 AM

Or the OP can just take out the intake and clean the throttle body and save money from repair shops.

Is your other hal's ride an auto as well? Is one a sedan and one an LB?

1nzfe engine is designed for 87 octane....not 89

what wheels/tires are on the car? a heavier setup would make it feel sluggish

maybe check the spark plugs? air filter? maf?

My bad.

malibuguy · 01-25-2012, 01:57 PM

I blame the e-throttle...

It seems to adapt to driving style...when i drive aggressive it quickens up a little bit...when im driving like im 87 years old to save gas its dull and delayed

I thuroughly enjoy my cable throttle for consistency

Have a real race. See if the car really is slower or if it only seems that way.
