IAC problem causing jerking
Every once in a while my check engine light comes on and it iss throwing the Idle Air control valve error. And what my car does is everytime I step on and let off the gas the car bucks kind of like if a person does not know how to drive a stick, but I am not using the clutch at all its just the gas pedal. Then It stops and a couple of days later the check engine light will turn off. It was not very bad before just anoying but it is getting worse and happening more often.
Is this the idle air control valve doing this
I don't want to fix it if it is not becasue it is $190 for a new one.
Any suggestions.
