. Replace the Engine Coolant Temperature (ECT) Sensor, located under the distributor.

. Clean Idle Air Control Valve (IACV), throttle body, and upper and lower ports.

. Replace Thermo Valve.

I replaced the throttle body already, where is the iacv located and where is the thermo valve located and if I replaced the throttle body do I need to clean it again, also you said to replace the etc wich is under the distributor, do I have to remove the distributor. And does that affect the idling. Thanks for all the help I really appreciate it thanks again

The IACV is located on the backside of the throttle body:

You shouldn't have to remove the distributor to get to the ECT Sensor. Just use a good light and you shouldn't have any problem. Yes, it can greatly affect idling if it's failing.

The thermo valve is located under the throttle body--it's not serviceable. Has wax inside that affects air flow, when it melts.

I really do appreciate all of your help with this particular vehicle, do you have a number I can contact you at or is it strictly email. I love the computer and all but find it better to have a conversation on the phone when it comes to problems with vehicle. I'll give you my number and email I'm from edmonton alberta canada and I am a used car dealer, I have an apprentice mechanin working for me and he's great to switch parts or anything like that but can't really diagnose a vehicle so again I do appreciate all the help with this.

My name is Paul Buro my email is [email protected] and my number is 780-488-4111 I have free long distance so I can call you back right away thank a
