Unless your repair involved replacement or modification of engine controls, such as the IAC valve or throttle position sensor, the instant you start the truck after replacing just a, or both, head gaskets, the engine should operate normally. If the idle speed is erratic, too high or too low, or engine operation is rough, you can request an engine diagnostic and the responding certified mechanic will diagnose the issue you are facing and resolve it. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
