Porsche 911 Turbo [964] (1991-94)

COMMON FAULTS
Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.

The Porsche 911 Turbo [964] (1991-94) had a few common faults that owners often encountered:

- **Electrical Issues**: Problems with the DME relay and ignition system were reported, leading to hard starts or intermittent power loss.
- **Turbocharger Problems**: Issues with the wastegate and diverter valve could affect boost pressure and performance.
- **Air Leaks**: Vacuum leaks in the intake system sometimes caused rough idling or stalling.
- **Distributor Drive Belt**: Failures in the distributor drive belt could lead to ignition problems.
- **Suspension Wear**: Components like bushings and shock absorbers were prone to wear over time.

These faults were typical of high-performance cars from the era and could often be resolved with proper maintenance.
