i have a auto corolla and when i put my foot flat to floor it doesnt rev as hard as it used to and doesnt seem to take off that much seems to have lost power i havent touched anything in it but i did put some of than petrol that contains like 10% ethanol in it like 1 month ago but it should of effected it straight away? lately ive just been using usual unleaded

Ethanol eats away at some plastics, don't use it, Its rubbish.

 

What model Corolla ?

1987 sedan cs or something

Sounds like a 4ac ae82.

How long since it has been serviced and tuned?

 

Maybe try running premium in it. I've always found it gives better power and fuel consumption in older cars.

4A's recommend a minimum of 97 octane, Can't remember if thats ron or mon.

check plugs, check compression, check catalytic converter hasn't disintegrated or blocked the exhaust.

Do you mean the auto doesn't kickdown? ie change down a gear? Because it should change down when you put your foot flat.

The ethanol can slowly destroy the plastic float in some carbs, so be wary of it.

Thats actually a good point, My initial read of his post i thought that it didnt like to free rev, When i first got my 4ac auto seca the kickdown cable was too far stretched so when i would go to take off it would only take off in second and be very slow and when you put your foot down it wouldnt kick down so it would just slowly speed up, I ended up just driving it like a manual for the 1st 2 days and then adjusted the cable now its all sweet.

id check the timing too.

ethanol petrol works better in my car. lol. but most the time 95 octane costs more than its worth. unless u go to the independant and its cheaper :lol:

Also watch out for the ethanol blend on freshly painted acrylic paint as it damages it
