Problems With Vvti- Engine Light On. Any Help?

[bosco]

Hello again,

Ive got a problem with my 2001 yaris T sport again. I put in some octane booster when my tank was full, forgot to do it at the same time as filling, anyway, about 5 miles later it starting going mad, reving to 3000 for no reason, cutting out, spluttering. About 5 miles later it corrected itself but the engine management light came on, didnt go off. I took it today to toyota and the code came up as a vvti controller/unit needs replacing. Its a days labour and will cost a fortune. I explained what I did and shouldnt of caused that. Its also using more petrol.

Should I wait to use all the remaining petrol and fill up with fresh petrol or use a fuel cleaner additive?

What is the correct course of action.

Any help please.

The head needs to be removed? Is there anything I could do?

Thanks.

Has it recently been serviced and is it using 5-30W oil?

I just changed the plugs to Bosch ones and the oil is about 5 months old.
