1999 Ford Bronco problems

Common 1999 Ford Bronco problems

The 1999 Ford Bronco, like any other vehicle, is prone to certain issues that its owners have reported. This article will discuss the most common problems with the 1999 Ford Bronco, including the ignition module failure, engine stalling, broken universal joints, ignition problems, oil pressure problems, and fuelling problems.

1. Ignition Module Failure
   Ignition module malfunctions are a common problem in the 1999 Ford Bronco. The ignition module is responsible for controlling the ignition system's spark timing. When it fails, the engine may misfire, stall, or have trouble starting. This issue can be caused by various factors, including wear and tear, overheating, and voltage fluctuations. Replacing the ignition module is the most common solution to this problem.
2. Engine Stalling
   Some 1999 Ford Bronco owners have reported that their engines stall at idle, especially when the vehicle is warm. This issue can be caused by a variety of factors, including faulty fuel injectors, a dirty throttle body, and vacuum leaks. In some cases, the problem can be resolved by cleaning the throttle body and fuel injectors or replacing the vacuum hoses. However, if the problem persists, it may be necessary to replace the engine control module (ECM) or the fuel pump.
3. Broken Universal Joints
   Broken universal joints (U-joints) are a common problem in the 1999 Ford Bronco, especially if the vehicle is used off-road. The U-joints connect the driveshaft to the differential and the transmission. When they break, the driveshaft can become disconnected, causing the vehicle to lose power. Replacing the broken U-joints is the most common solution to this problem.
4. Ignition Problems
   Some 1999 Ford Bronco owners have reported that their engines die when they are driving along or when they reach an intersection. The engine then won't restart. This issue has been traced to a faulty TFI module, which controls the ignition system's timing. Replacing the TFI module is the most common solution to this problem.
5. Oil Pressure Problems
   On occasion, the 1999 Ford Bronco may suffer from oil pressure problems, making it seem like the engine has no oil pressure when warm. However, the problem has been traced to faulty oil pressure switches, and the replacement of the switch is covered in the Haynes Bronco manual.
6. Fuelling Problems
   Ford used just two studs to attach the 300ci carburetor in the 1999 Ford Bronco. Over time, the carburetor rocks, which can cause the gasket it sits on to fail, leading to poor fuelling. The solution is to replace the gasket and tighten the nuts to the required torque, a procedure you'll find in your Haynes Bronco manual.

In conclusion, while the 1999 Ford Bronco is a reliable SUV, it is prone to certain issues that its owners have reported. These problems include ignition module failure, engine stalling, broken universal joints, ignition problems, oil pressure problems, and fuelling problems. Being aware of these issues can help potential buyers make informed decisions and avoid costly repairs.
