Loss power after gas fill up HELP!
 

Filled 91 v power (no ethanol), hour later noticed significant power loss..it's taking awhile for the rpms to climb...car has 4000km no oil change..did I get bad gas...or is something more serious ie maf sensor fuel pump/fuel filter..it takes awhile for those things to go bad right...

It could be bad gas, maybe leading to fouled plugs and injectors. Maybe water in the fuel. Hard to tell.

The gas cap is properly secured, right?

Is someone hiding in the trunk? Seriously though i noticed power loss (lack of) when carrying 3 cases of beer in this thing. I always use Shell VPower. no issues yet.

Yes gas cap is secured. Even went back to that station and made sure that I didn't pick the wrong grade since I started doubting myself if I put the v power or not and I did choose the correct on.

Fouled plug and injectors would give me CEL which I don't. I even plugged my obd reader just to make sure and nothing. And foul plugs and injectors aren't these all too early for a 4000km car...

No no I made sure! Ive been using vpower from day one..no crickets either so I was happy until now

Could try some octane booster to try to level out lower grade fuel. It may take more than one bottle. I've had to do this before on another vehicle.

Weird problem, for sure.

Yeah I'm actually thinking of doing that already

Thanks

Not to be a stick in the mud but doesnt each bottle raise the octane by like 0.3? so to go from 87-90 thats 30 bottles? Octane doesnt make power it just prevents knock. Look elsewhere before wasting money on octane booster. Take it to dealer if it gets real bad. But unless its knocking (banging) the octane is fine.

Have it check with your dealership since still under waranty.
So they my have a good look on the engine, if the fuel is not a problem.

I actually did take it up to the dealer already..they weren't very helpful..It took a few
Emails to scion Canada and dealers service manager to even get a call back..service has been in contact with fuel experts and instructed me to finish the "bad gas" I got and fill Up high octane 94..Mechanic test drove it but he couldnt give me an answer in terms of verifying the issue."need to get another frs manual to compare" Thats when I decided to email scion and dealer manager..still half a tank of this gas and will go with 94 from there

x 2.

I was expecting them to do that..the service foreman basically gave me my keys and told me he'll be consulting with engineers And call me back..waited all day and he didn't call me back...that's when I emailed head office/dealer manager..that's when he decided to call me back the next day aware of my emails..He instructed me to finish the tank and use 94 and going from there

Let's not overdo it. You just noticed a slight power loss after fueling. Okay. Take a minute and check a few things. Maybe a hose came loose under the hood. Maybe there's something blocking your air intake. Try to relax and think things through before you call the president of Toyota and demand a new car. It doesn't sound serious yet.

I am not demanding for a new car..the problem was they didn't even check anything under the hood. I asked if I could leave the car at the dealership but they refused..i guess that was not their protocol... I'm worried about the car and I just wanted them to treat the issue with some urgency...
