forgot to mention the code is threw was an iavc code

 

Idle problem: You may have an intake air or vacuum leak.

Fan problem: "Jumper wire" the connector to the coolant temperature switch on the thermostat housing. The fan should run continuously. If not, the fan relay or fan motor is bad. You can test the fan motor by providing it with battery power.

 

how exactly do i test it with a battery power??

Wire the motor directly to the positive and negative battery teminals.

 

cool thnx , i found my main idle problem there was a vac leak on the bottom of the TB.

The idle sticks sometimes , i cleaned the TB but when the rpms go down sometimes it gets stuck on 1500-2k rpms so i just tap the gas for it to go down why does it stick??

 

If you think the TB is fine, then your throttle cable may be sticking. Check whether the throttle cable needs adjusting - yours may be a bit too tight.
