Frequently Asked Questions

What is an IACV and why is it important?

IACV stands for Idle Air Control Valve. It regulates the amount of air bypassing the throttle plate to maintain a steady engine idle speed. A faulty IACV can cause rough idling, stalling, or fluctuating RPMs.

Are repair manuals still necessary in the digital age?

Yes. While online resources are helpful, dedicated repair manuals (like Chilton’s or specialized engine books) provide comprehensive, organized, and verified technical specifications, torque settings, and detailed diagrams specific to your vehicle model that are often difficult to find reliably elsewhere.

How do I know if I need a new window channel guide?

If your power window operates slowly, binds, rattles, or struggles to move smoothly up and down within the door frame, the window channel guides or rollers are likely worn out and need replacement.
