Nervous Setting Off

[Mikey Mechanic]

i've just got a yaris sr 1.3, an setting off in first 1 in 3 times it takes a while to raise the revs even with the foot to the floor

i've replaced the spark plugs, put on a new air filter, serviced it, used fuel flush, reset ecu an kicked tyres an its still done nothing i'm thinking it might be fuel sender unit but don't know

anyone got any ideas?

cheers

Have you cleaned the MAF sensor?

[Mikey Mechanic]

how do you clean it?

[HowardL]

how do you clean it?

I aint done it myself (yet)

But someone on here may well explain

All I know it's easy but a bit on the delicate side

[stantheman1]

how do you clean it?

This has been covered before, if you type in the above search bar: P0171 System To Lean (bank 1), I need to troubleshoot a P0171 error. (spelling it exactly the same, eg To instead of Too)

You should then see a page with 9 results, choose the 3rd (18 posts - 17 authors) then go to page number 2 and scroll down to the post written by georgincanada (oct 23 2004)

Follow his instructions ( with pictures) and you wont go wrong.

Hope this helps

PS

I don't think that this will cure your fault,(usual fault cured by this method is low idle revs) but there is no harm in cleaning the sensor as it should improve idle.

This could be the bouncing clutch problem,does it happen with drive engaged or in neutral?

[Mikey Mechanic]

it happens both in drive an in neutral it feels as though its starved of fuel or something along them lines am gonna clean maf meter 2moro an see if that helps

does it splutter or the revs just take ages to rise?

[Mikey Mechanic]
