I have this problem too taken my car to toyota like 6 times!! toyota is ****** they cant find wats wrong wit it ... they lifted my idle up manually ... but when its cold it will still drop an start shakin under 500 idunno why it does this ... its ****** i hate it ... makes me so angry ...
I think we should all do something about this problem .... Its a common problem with the corolla an toyota know it.. But they won't admit to it ...
if more an more people complain they have to find the problem and fix it! print this thread out an take it to toyota show them that its not only u wit this problem ....
