Common 1991 Dodge Dodge truck problems

The 1991 Dodge D150 has been reported to have several common problems based on complaints from owners.

One of the most common issues is related to the stock radio. Some owners have reported that the radio simply does not work, with no buttons functioning or any sound coming from the speakers. It is unclear if the problem is with the head unit or with the speakers themselves, but it is recommended to check the connections in the back of the head unit to ensure they are tight. Additionally, there is no way to check the speakers without an external audio source, so it is recommended to test the speakers with a different audio source to determine if the problem is with the speakers or the radio.

Another common problem is related to the u-joints, which can cause a shake once the truck reaches 100km/h. This issue is not unique to the 1991 Dodge D150, as it has been reported in other model years as well.

The 3.9L V-6 engine, which was used in the 1991 Dodge D150, has been reported to have several issues. One of the most common problems is a vacuum leak at the "belly pan gasket" on the intake manifold, which can cause stumbling and poor idle after a warm restart, and "pops" when the throttle is "blipped." This problem can be identified by checking for black residue, either wet or dry, at the bottom of the throttle body. Another issue with the 3.9L V-6 engine is weak or intermittent grounds, which can cause "weird electrical issues."

Additionally, the 3.9L V-6 engine has been reported to have issues with fuel injection. In 1988-1991, the engine used single-point electronic fuel injection, which can cause stumbling and poor idle after a warm restart. In 1992-1996, the engine used multiple-point fuel injection, which can also cause stumbling and poor idle. In 1997, the engine received sequential multiple-port fuel injection, which increased responsiveness but did not increase horsepower or torque.

The 1991 Dodge D150 has also been reported to have issues with aftermarket parts. Specifically, there are no box liners, tonneau covers, or lowering suspension parts available for the truck. This can make it difficult for owners to customize or repair their trucks.

Finally, the 1991 Dodge D150 has been reported to have issues with the engine dying when sitting idle. This issue has been reported to occur after the engine has been running for a while and then stops, even after the ignition is turned off and then back on. The problem is believed to be related to extreme heat and a lack of air movement, and it is recommended to let the engine cool down before attempting to start it again.

In conclusion, the 1991 Dodge D150 has several common problems based on complaints from owners. These include issues with the stock radio, u-joints, the 3.9L V-6 engine, aftermarket parts, and the engine dying when sitting idle. It is important for owners to be aware of these issues and to take appropriate steps to address them.
