Whether restoring a classic Celica to its original glory or upgrading an existing setup for improved throttle response and fuel efficiency, this remanufactured injector delivers **consistent performance, enhanced reliability, and peace of mind**. Built to withstand the demands of modern fuel formulations while maintaining the integrity of Toyota s original design, the **GB 842-12139** is a trusted choice for enthusiasts seeking a balance of **cost-effectiveness, durability, and performance** in their fuel delivery system.

**Pros and Cons of Buying a Genuine Parts (GB) Remanufactured Port Fuel Injector (Part Number 842-12139) for a 1986-1987 Toyota Celica**

1. **Reliability and Performance** Remanufactured injectors from a reputable supplier like Genuine Parts are rebuilt to factory specifications, ensuring they function similarly to new OEM parts. This can restore proper fuel delivery, improve engine performance, and reduce issues like misfires or rough idling.

2. **Cost-Effective Alternative to OEM** While not an exact OEM part, a remanufactured injector is significantly cheaper than a brand-new OEM unit. This makes it a practical choice for budget-conscious owners who still want quality.

3. **Compatibility** The part number (842-12139) is designed specifically for the 1986-1987 Toyota Celica, ensuring a proper fit without modification. This reduces the risk of installation errors or compatibility issues.

4. **Warranty Coverage** Genuine Parts often provides a warranty (typically 6-12 months) on remanufactured components, offering some protection against premature failure.

5. **Easier Availability** Remanufactured injectors are generally easier to source than OEM parts, especially for older vehicles, reducing wait times for replacement.

6. **Environmentally Friendly** Purchasing a remanufactured part supports recycling efforts by extending the life of existing components rather than contributing to e-waste.

---

1. **Variable Quality** Not all remanufactured parts are created equal. While Genuine Parts is a trusted brand, there is still a risk of inferior rebuilds if the supplier cuts corners on cleaning, testing, or component replacement. This could lead to premature failure or inconsistent performance.

2. **No Original Warranty** Unlike new OEM parts, remanufactured injectors do not come with Toyota s original warranty, meaning you bear full responsibility for any issues post-installation.

3. **Potential for Contamination** If the injector was not properly cleaned during remanufacturing, residual carbon, debris, or old fuel deposits could remain, leading to clogging or poor atomization over time.

4. **Limited Longevity Compared to New OEM** While remanufactured injectors are durable, they may not last as long as a brand-new OEM part, especially if the vehicle is driven aggressively or in harsh conditions.

5. **Dependence on Supplier Reputation** The quality of the remanufactured part depends heavily on the supplier. If Genuine Parts has a poor batch or mishandles the unit, the injector may underperform or fail quickly.

6. **Additional Costs** Beyond the injector itself, you may need to budget for professional installation, testing (e.g., fuel pressure tester), and potential related repairs (e.g., cleaning the fuel system or replacing a faulty fuel pump).

A Genuine Parts remanufactured port fuel injector (842-12139) for your 1986-1987 Toyota Celica is a **practical and cost-effective solution** for restoring engine performance, especially if the original injector is failing or clogged. The part offers a balance between affordability and reliability, provided it is sourced from a reputable supplier and installed correctly. However, it is not without risks quality variability, lack of OEM warranty, and potential hidden issues require due diligence.

For the best results, **verify the supplier s reputation**, ensure the injector is thoroughly tested before purchase, and consider having a professional inspect the fuel system (including injectors, fuel lines, and the fuel pump) during installation. If budget allows, pairing the remanufactured injector with a fuel system flush or new fuel filter can further mitigate risks.

- **Proceed with purchase** if you are confident in the supplier s quality and willing to invest in proper installation and post-purchase checks.

- **Consider an OEM or high-quality aftermarket alternative** (e.g., from Stanadyne or Delphi) if budget permits, as these may offer longer warranties and more consistent performance.

- **Test the injector** (if possible) for proper spray pattern and resistance before installation to avoid surprises.

- **Monitor the engine s performance** after installation. If issues persist (e.g., rough idling, poor acceleration), have the injectors professionally scanned or replaced.

Ultimately, a remanufactured Genuine Parts injector is a **solid choice for most Celica owners**, but it should not be treated as a "set-and-forget" solution without proper maintenance.
