First, I would check to make sure there are no bubbles in the system which may be preventing the fan from functioning correctly. Then, I would replace the thermostat. They are so cheap, that you might as well. You can test it by suspending it in water and looking to see if it opens when the water reaches the temperature rating of the thermostat.
Where does the ECT gauge hover when driving normally?
About the idling problem, when was the last time you did a tuneup with new wires, spark plugs, distributor cap/rotor? Have you thought about running a bottle of injector cleaner through?
Sorry I couldn't be more help. I will flip through my service manual and see if I can find anything relevant to your problems.
okay, i was wondering...i have one of those aftermarket radiator caps that have a button int he middle and when i press it, it releases air/pressure?
is that actually bad for the system?
i already bought a thermostat, im just waiting to replace it after my smog check. a rad fan and motor is ont he way as well.
i already replaced the distributor, o2 sensor, PCV valve, plugs, plug wires, main relay and checked the injectors for clicking.
i run fuel injector cleaner every tank (have a whole gallon of mystery oil
