Hi all..How are you?I have an overhating and idle problem.I did my timing belt and waterpump.I also changed my thermostat 3 times..and bleed the anitfreeze for air.the problem that im having is,when the car is warmed up and i drive it for 30 mins,when i come to a stop at red light or parking the vehicle,the car starts to overheat(gauge starts to rise),and the idle starts to rise(gas pedal sticks),idles erratically to 2500rpms then drops to nornal (continously),until i turn it off..but when im off on the road again the same thing..If anyone knows what the problem could be i will greatly apprecaite it.Thank you.

 

Does the fan fail to run when you're stopped & idling? If so, maybe a bad fan switch (in the thermostat housing).

Unplug it, jumper the wire with a paperclip. Key on, that should make the fan run. If it runs, then all the rest of the circuit (relay, fuse, fan motor, etc) is OK.
