Parts for your 1988 Mitsubishi Pajero-Ignition coils

1988 Mitsubishi Pajero ignition coils — fitted on petrol models, not used on diesels

Based on technical literature, a 1988 Mitsubishi Pajero with a petrol engine uses a single canister-style ignition coil feeding a distributor, while diesel variants do not use an ignition coil at all. This is confirmed by the Mitsubishi Pajero/Montero Factory Service Manual for the first-generation L040 series (Ignition System section) and popular repair guides such as the Haynes Mitsubishi Pajero/Montero 1983–1996 manual, both of which show a conventional coil-and-distributor setup on petrol engines (e.g., 4G54 2.6 and 6G72 3.0 V6). Diesel Pajeros (e.g., 4D56) operate by compression ignition and therefore have no ignition coil, consistent with standard diesel principles outlined in the Bosch Automotive Handbook.

For petrol 1988 Pajero models, the ignition coil’s whole job is to transform the battery’s 12 volts into the high voltage needed to jump the spark plug gaps. On these older Mitsis it’s a single, cylindrical coil working with the distributor and an igniter module, not a coil-on-plug or modern coil pack. When it’s healthy, the engine fires cleanly, idles smoothly, and pulls well under load, when it’s tired, you’ll often cop hard starts, misfires, rough idle, and a noticeable lack of grunt, especially up hills.

As part of routine servicing, it’s smart to give the ignition coil and its mates a once-over. Look for oil leaks from the coil body, cracked housings, loose terminals, and green or powdery corrosion at the connectors. Because the coil lives in a hot bay, heat cycling can fatigue internal windings over time. If you’re chasing an intermittent misfire, a resistance test with a multimeter (using the factory manual’s specs) can help pinpoint a failing coil, but remember that a coil can pass a cold resistance test and still break down under heat. If you’re replacing the coil, match it to your exact engine code and ignition system, as some setups use a specific primary resistance and may incorporate an external ballast resistor or resistor wire. It pays to renew the high-tension lead from coil to distributor at the same time, and check the distributor cap, rotor, and spark plug leads—weak links here can make a good coil look bad.

• Common symptoms: hard starting, misfire under load, rough idle, poor fuel economy, and backfiring on overrun.
• Good habits: keep terminals clean and tight, inspect leads for cracks, avoid pressure-washing the coil area, and verify correct plug gaps.
• Service tip: if one ignition component fails on an older system, inspect the whole chain—coil, leads, cap, rotor, plugs, and engine earths.

If your 1988 Pajero is diesel, there’s no ignition coil to service—focus instead on glow plugs, fuel filtration, and injector health.

Does a 1988 Pajero have an ignition coil?

Petrol models do—one conventional canister coil feeding a distributor and igniter. Diesel models don’t use an ignition coil because they ignite fuel by compression rather than spark.

What are the signs of a failing coil on a petrol 1988 Pajero?

Cold-start misfires, stumbling under load, rough idle, and worse fuel use. Visual clues include oil seepage from the coil body and corroded terminals. Testing resistance against the factory specs and substituting a known-good coil are common diagnostic steps.

How often should the ignition coil be replaced or checked?

There’s no fixed interval, check it at regular services, especially if chasing misfires. Many owners replace the coil proactively once it shows heat-related issues or if other ignition components are being refreshed.
