I have checked the idle speed control valve and disconnected the plug to it...no change in idle speed.
I have also discovered that the thermostat has been removed. The car takes forever to warm up and the temp guage barely reaches 80 degrees after driving for a while. I have checked the resistance reading on the coolant temp sensor and it was at 2.2kohm when the car was cold....55 degrees or so ambiant temperature. would the lack of thermostat create that issue or they are seperate? I am ordering a thermostat but should i order an idle speed valve too???

Thanks guys for all your input..much appreciated
