The 1988 Fifth Avenue likely used a single-coil ignition system *within the distributor* for the Lean Burn system, but there were different configurations of the distributor itself, leading to the confusion. Some sources might incorrectly refer to "dual-coil" because the ignition system *overall* managed two separate circuits (one for the lean burn, one for non-lean burn situations depending on sensor input), even though only one coil was physically present inside the distributor.
To be certain about your specific vehicle, you need to check the following:
* Your vehicle's VIN: This will allow you to look up the exact specifications and confirm the ignition system used.
* The distributor itself: Physically examining the distributor cap will show you whether there is one or more coil(s) inside.
* The parts diagrams: Check a Chrysler parts catalog (available online or at a parts store) for your specific VIN. This is the most reliable method.
Don't rely solely on generic online information. The lean burn system variations make generalizations unreliable. Focus on verifying the specifics for your individual vehicle.
