Idle problem!! Help!!

[Panda_Tureno86]

Hey guys. Need advice here.
My 4AGE 16V is idling at 3k all the time.
No matter hot or cold.
And the temp gauge shows colD all the time.
Engine revs fine.
Temp sensor maybe??

Could be several things
1) Air bubble in the cooling system - sits in the highest point (throttle body) and doesn't allow the wax pellet cold idle valve to close. Jack the front of the car up and bleed the coolant
2) Wax pellet cold idle valve busted/jammed - Remove and clean, or replace, or just bin and blank off the holes
3) Thermostat jammed open - doesn't allow coolant to get up to temperature, so car always cold and wax pellet valve doesn't close.

All 3 of those are common 4AGE problems, I'd look at them before assuming it's a sensor issue.

^^^^as Hiro has said, 100% agree. what is the motor in? Is this problem due to an engine conversion, or has it just started?

cheers,
matty.

Well. I just bought this AE86
Not even sure if it has a big port or small port.
Where is this wax pallet, cold idle valve thingy?
Anyone got a a pic of where it is?
Can I remove it and block it off?
Reason I said might be the sensor was becaus on the water temp guage it's always on the cold side. Even after I drove it for 30mins.

Its a little better. Now down to 2k.
Suppose I should clean it out more??
I cleaned it with Carbu cleaner
