Here's a breakdown of the difficulty:
Factors that make it relatively easy:
* Accessibility: The IAC valve on the Aspire is usually fairly accessible, located on the throttle body. You shouldn't have to remove a lot of other components to reach it.
* Simple removal: It typically involves disconnecting a couple of electrical connectors and possibly a vacuum line, then unscrewing it from the throttle body.
* Cleaning is straightforward: Cleaning usually involves using carb cleaner (following safety precautions!) and a small brush or compressed air to remove carbon buildup.
Factors that might add to the difficulty:
* Rust or seized fasteners: If the bolts holding the IAC valve are rusted or seized, removing them can be challenging. Penetrating oil can help.
* Electrical connector stubbornness: Sometimes the electrical connectors can be difficult to disconnect, especially if they're old and brittle. Gentle persuasion is key—avoid excessive force.
* Throttle body cleaning: While not strictly part of IAC valve cleaning, it's a good opportunity to clean the throttle body while you're there. This adds a little more time and effort.
* Lack of experience: If you've never worked on a car before, it might take longer to familiarize yourself with the process.
Overall: With a bit of patience and the right tools (sockets, screwdrivers, penetrating oil, carb cleaner, brushes), most people can successfully remove, clean, and reinstall the IAC valve on a 1997 Ford Aspire. However, if you're uncomfortable working on your car, it's always best to consult a mechanic. A YouTube search for "1997 Ford Aspire IAC valve cleaning" might provide helpful visual guidance.
