Review FORD TRUCK Electronic Throttle Accelerator Pedal From 6.8l At fits EXCURSION 2005

The **Ford 546.FD8S05 Throttle Accelerator Pedal** is a high-quality, direct-fit replacement part designed specifically for the **2005 Ford Excursion** equipped with the **6.8L Triton V10 engine**, matching the original equipment manufacturer (OEM) specifications for unmatched performance and reliability. This pedal assembly is engineered to replicate the precise dimensions, material composition, and operational mechanics of the factory unit, ensuring seamless integration with the vehicle s throttle linkage system. Crafted from durable, corrosion-resistant materials, including reinforced steel and high-grade plastics, this pedal is built to withstand the rigorous demands of heavy-duty towing, off-road adventures, and daily driving, all while maintaining smooth, responsive acceleration. The **10143764** part number guarantees compatibility with the Excursion s powertrain control module (PCM) and throttle-by-wire (if applicable) systems, eliminating the risk of calibration or fitment issues. Whether restoring a classic Excursion or upgrading an existing vehicle, this pedal delivers the precision and durability expected from Ford s performance-oriented lineup, ensuring consistent throttle response and optimal engine performance under all driving conditions.

### **Pros and Cons of Buying a 2005 Ford Excursion with a 6.8L Engine (VIN 10143764) and a Throttle Accelerator Pedal Issue**

1. **Powerful Engine** The 6.8L Triton V10 engine is one of the most robust and reliable Ford V10s, capable of producing strong towing and hauling power. With proper maintenance, it can last well beyond 200,000 miles.

2. **Full-Size SUV Platform** The Excursion is built on the same frame as the F-250 Super Duty, meaning it has a heavy-duty suspension, strong frame, and better ground clearance than most SUVs of its time. This makes it suitable for off-road use and heavy loads.

3. **High Ground Clearance & Approach/Departure Angles** The Excursion has a higher ride height than most SUVs, allowing for better off-road capability and easier access to cargo or bed space.

4. **Strong Resale Value (for Collectors)** While not a common vehicle today, the Excursion holds some niche appeal among truck and SUV enthusiasts, particularly the V10 models. This could make it easier to resell in the future if maintained well.

5. **Available Off-Road Packages** Some Excursions came with optional off-road packages, including skid plates, heavy-duty suspension, and locking rear differentials, which could enhance its utility.

6. **Spacious Interior** The Excursion offers a large cabin with ample seating for seven passengers, making it practical for families or groups.

7. **Durability of Ford s Heavy-Duty Components** Many parts, such as the transmission (if it s a 4R100 or 4R70W), frame rails, and drivetrain, are built to last, especially if they ve been well-maintained.

1. **Throttle Accelerator Pedal Issue** The fact that the throttle accelerator pedal is failing or needs replacement is a **major red flag**. Throttle issues can lead to:

- Unintended acceleration (a serious safety hazard).

- Difficulty controlling speed, especially on hills or in traffic.

- Potential failure of the throttle body or pedal assembly, which could require costly repairs.

- If the issue is electrical (e.g., faulty throttle position sensor or wiring), it may indicate neglect or a larger underlying problem.

**This is likely the biggest concern** if the pedal is not functioning properly, the vehicle may not be street-legal or safe to drive until fixed.

2. **High Maintenance Costs** The V10 engine, while powerful, is **thirsty for oil and fuel** and has more moving parts than a smaller engine. Common issues include:

- Oil consumption (some V10s burn oil excessively).

- Valve cover gasket leaks.

- Timing chain stretch or failure (if not serviced regularly).

- Suspension wear due to the heavy weight.

Parts and labor for a full-size SUV are expensive, and repairs can add up quickly.

3. **Poor Fuel Economy** The Excursion is **not fuel-efficient**, especially with a V10. Expect **around 10-12 MPG combined**, making it costly to operate over long distances.

- Electrical gremlins (common in older Fords).

- Suspension and steering issues (ball joints, tie rods, bushings).

- Transmission problems (especially if it s an automatic with high mileage).

- Poorly insulated cabins (noise and cold in winter).

5. **High Insurance Costs** Due to its size, weight, and power, insurance for an Excursion is **significantly more expensive** than for a smaller SUV or truck.

6. **Limited Availability of Parts & Mechanics** As a discontinued model, finding specialized parts (especially for the Excursion-specific components) can be difficult. Not all mechanics are familiar with the V10 or the Excursion s unique systems.

7. **Safety & Crash Test Ratings** The Excursion was **not well-rated in crash tests** (NHTSA gave it poor scores for frontal and side impacts). Its size and weight also make it harder to maneuver in tight spaces.

8. **Depreciation** The Excursion has **depreciated heavily** over the years, and even a well-maintained one may not hold much value unless it s a rare or modified version.

9. **Weight & Handling** At **over 7,000 lbs** (especially with a crew cab), the Excursion is **heavy and sluggish** in city driving. It requires more space to turn and can be difficult to park.

10. **Environmental & Practical Drawbacks** The V10 is **loud, smoky, and polluting** compared to modern diesel or hybrid options. It s also **not ideal for daily driving** due to its rough ride and high operating costs.

### **Conclusion & Recommendation**

#### **Should You Buy This 2005 Ford Excursion?**

- You **need a heavy-duty, off-road-capable vehicle** for extreme conditions (e.g., farming, construction, or serious off-roading).

- You **have the budget for repairs** and are prepared for high maintenance costs.

- You **plan to keep it for a short term** (e.g., 1-2 years) and then sell it for parts or as a project.

- You **find a well-documented history** with **full service records**, especially for the V10, transmission, and suspension.

- The **throttle issue is isolated** (e.g., just the pedal or throttle body) and can be **easily fixed** (not a wiring or ECU problem).

- You **don t mind high insurance and fuel costs** and are okay with a rough ride.

- You **need a reliable, low-maintenance daily driver** this is **not** that vehicle.

- The **throttle issue is severe or electrical**, as it could indicate deeper problems.

- You **can t afford unexpected repairs** (the V10 and suspension alone can cost **$3,000 $10,000 ** in maintenance over a few years).

- You **prioritize fuel efficiency, safety, or modern technology** this Excursion is **outdated in every way**.

- The **odometer is extremely high (200,000 miles)** without proof of maintenance.

- You **can t find a pre-purchase inspection (PPI) from a trusted mechanic**.

- The **throttle system** (pedal, throttle body, wiring, TPS sensor).

- **Engine condition** (oil leaks, compression, timing chain wear).

- **Transmission** (fluid condition, shifting smoothness).

- **Suspension & steering** (ball joints, bushings, shocks).

- **Frame & undercarriage** (rust, damage, skid plates if installed).

- **Electrical system** (common issue in older Fords).

2. **Negotiate Based on Findings** If the PPI reveals **major issues beyond the throttle pedal**, use them to **lower the price** or walk away.

- **Used Ram 2500/3500 (2010 )** More reliable, better fuel economy, and easier to maintain.

- **Used Ford F-250 Super Duty (2011 )** Similar to the Excursion but more practical.

- **Diesel Trucks (Ram 6.7L Cummins, Ford 6.7L Power Stroke)** More efficient and durable long-term.

- **Used Toyota Tundra (2015 )** More reliable and better resale value.

- **Budget for immediate repairs** (throttle system, fluids, tires, brakes).

- **Expect high long-term costs** (V10 maintenance, suspension, electrical).

- **Insure it properly** (expect **$200 $500/month** for full coverage).

- **Use it sparingly** (not for daily commuting unless you love rough rides).

- You **absolutely need its off-road capability** and can afford its drawbacks.

- The **throttle issue is minor and fixable** (not a sign of neglect).

- You **have the funds for repairs and high operating costs**.

**Otherwise, look for a more modern, reliable alternative.** The Excursion is a **fun but expensive hobby vehicle**, not a practical daily driver. If you re buying it for **utility,
