having an intermittent problem with the 3sge in the missuses celica
when its cold it starts and runs fine but after a while of being warm it seems to drpo a cylinder, idle rises to about 1600rpm and there is no power when you try to accelerate away from a standstill until about 3000rpm.
then if you stop it it wont start again until its cooled down.
i changed the plugs and leads and its still doing it.
anyone have any other ideas what it might be?
