Signs of Failing Spark Plugs
When your Rampage's spark plugs are worn, the signs are usually clear. Because these vehicles have simpler, pre-OBD-II ignition systems, you won't get a specific error code on a dashboard display. Instead, you need to pay attention to how your truck is running. Look for these common symptoms:
- Rough Idle: The engine shakes or sputters when you're stopped.
- Engine Misfires: You may feel a hesitation or stumble during acceleration. This can happen when a cylinder fails to fire correctly.
- Hard Starting: The engine cranks for a long time before it turns over, especially when cold.
- Poor Fuel Economy: Inefficient spark leads to incomplete fuel combustion, meaning you'll be visiting the gas station more often.
- Sluggish Acceleration: If your Rampage feels weak or slow to respond, worn plugs could be the cause.
No Specific Recalls or TSBs
Extensive searches of NHTSA records and Technical Service Bulletins (TSBs) show no specific recalls or service bulletins for spark plugs on the 1982-1984 Dodge Rampage. Any issues you experience are almost certainly due to normal wear and tear on these routine maintenance parts.
Choosing the Right Aftermarket Spark Plug
For a classic vehicle like the Dodge Rampage, choosing the right type of spark plug is more important than just picking the most expensive one. The original ignition system was designed for standard copper-core spark plugs, and it performs best with them.
Stick with Copper Plugs
Avoid the temptation to "upgrade" to modern platinum or iridium spark plugs. While they last longer in modern cars, the ignition system in your Rampage was not designed for them. You will get the best performance and value by using standard copper-core plugs and replacing them more frequently (every 15,000-20,000 miles).
