Post by: jbturgeon on March 20, 2009, 04:08:01 pm

Hi, i am wondering why my idle become high and stay high when my engine is at running temp. The idle is totaly normal when i start the car.

i think the pump just needs some tweaking.

What do you mean tweaking? Idle screw adjustment, pump moving with the adjusting screw?

What kind of tweak?

idle screw adjustment.  although it could be too much residual... the pumps are really finnicky.

When it's idling high, check to see if the fast idle is sticking on. It's on the back of the pump, connected to a long vertical rod.
