common faults in ram 1500

There are many systems to ensure that your vehicle’s engine works as designed. It is often assumed that the engine runs smoothly until a problem arises and the problem must be diagnosed by the operator. A misfire is often attributed to ignition timing when, in fact, there are several reasons why the engine could be running poorly. If you are in the unfortunate position of having a misfire on your Dodge Ram, understand that there are many reasons why your vehicle could be malfunctioning.

Ignition system, dodge ram 1500 faults

The first process to investigate when a misfire is detected is the ignition system. It consists of the timing, distributor, coil, spark plugs, spark plug wires, and electrical components, including the charging system. As these components begin to fail, the initial failure will be very minor and difficult to detect. As components deteriorate into a more advanced case of faulty repair, the problem will become more noticeable. If not supervised, this can lead to a complete failure and the vehicle will stop working completely. Popping noises through the intake manifold, sharp climbs, and jerks accompanied by rough idle and poor acceleration are all signs of an ignition problem. A periodic inspection of the ignition system is recommended to avoid such ignition difficulty. Check the spark plug wires for damage and make sure they are tight. Inspect the coil packs and / or the distributor for damage and wear. If your vehicle is equipped with a distributor, you should also check if the rotor is damaged or worn. Check the timing with a timing light to make sure it is within specification.

Lean misfire, ram 1500 misfire

Another common reason and generally missed diagnosis for a poorly running engine is lean misfire. In this case, the engine is getting too much air and there is not enough fuel. This is most noticeable when the engine is idling, as this is when an engine generally requires more fuel to run smoothly. The poor misfire condition is likely to disappear at highway speeds due to the more efficient flow to the combustion chambers. Some of the causes of a lean condition are EGR valves that are stuck in the open position, leaking intake manifold gaskets, faulty mass air flow sensors if your vehicle is so equipped, and exhaust filters. clogged fuel and faulty fuel pumps. Vacuum leaks are also to blame for some poor engine conditions. A thorough inspection of your rubber intake pipe, as well as periodic changes to your fuel filter and cleaning of your fuel injectors, are invaluable in anticipating any fuel-related problems with your vehicle. Again, it is much better and in most cases more profitable to be proactive rather than reactive in the maintenance department.

Mechanical misfire, common dodge ram 1500 faults

Perhaps the most costly misfire to correct is the mechanical misfire. This problem is related to a defect in the internal components of the engine. Bad head gaskets, worn piston rings, bad valves, and worn cylinder walls are all to blame. Damaged or broken rocker arms, broken valve springs, and worn camshaft lobes or lifters are also causes of mechanical misfires. Most of these faults will be accompanied by some kind of internal engine noise. A worn timing chain will often vibrate when it hits the timing cover, and a broken rocker arm will sound like a large piece of metal is rattling inside the top of the engine. Other faults, such as a broken valve spring, may not make any noise other than engine noise. These mechanical failures are often heard as a more constant noise and, in most cases, will increase in relative equality with the speed of the vehicle’s engine. Timely oil changes and periodic maintenance of your Dodge’s power train are required to help prevent this type of failure.
