Best Answer

if its sticking it will set a trouble code, some parts stores will obd2 scan for free.

if its stuck shut you will have detonation(knocking) and higher than normal operating temperature(overheating/low coolant)

stuck open hard to start (cold blooded)

its not just that simple

but you can clean it with a brush and see

but since you got it off replace it and save yourself any further headaches
