No you can't adjust idle. If it's gettinghot check radiator for beinggood and if you have a loss of coolant. If you do have it pressure checked for bad intakek/head gaskets

Then best thing to do is to check yoru fuel pressure as the pump may be getting hot and not pumping enough pressure. We have no info for this car so I don't have apressure togive you as to what it should be.
