Chevrolet Cruze Misfire: Fixed With an OEM Ignition Coil, Same Day

A returning customer messaged us in the morning. He had repaired his engine with us before, and now the same Chevrolet Cruze was stuttering. The car felt like it was hesitating and running rough, the kind of stumble you feel through the seat at idle and when pulling away.

He asked if he could come down that morning to get it diagnosed. He also mentioned the car had only a few months left before scrap, so he did not want to overspend. That is a fair and common situation in Singapore, where a car near the end of its COE still needs to run reliably for the time that is left. The goal was a proper fix at a sensible cost, not a full restoration.

When the car came in, we scanned it and checked which cylinder was misfiring, then tested the ignition side. The coil was on its way out. It was still firing enough to run, but weakly and inconsistently, which is exactly what produces a stutter that comes and goes.

We caught it before it failed completely. A coil that is going will often strand you when it finally dies, usually at the worst time. Picking it up early on the scan meant we could tell the owner clearly: this coil is about to give up, replacing it now will fix the stutter and save you a breakdown. No guesswork, no throwing parts at it.

We offered the owner two options and let him choose:

• Original coil set: quoted at $850, the original manufacturer part.
• OEM coil set: $680 including labour, a quality equivalent made to the same specification.

With only a few months left before scrap, the owner chose the OEM set, which was the practical call. We replaced the coils, cleared the misfire codes, and tested the engine until it idled and pulled smoothly with no stutter.

The whole job was done the same day, within a few hours of him dropping the car off. He drove it home that evening, and on the follow-up he said it was running well again.

What an ignition coil replacement costs depends on whether you choose original or OEM parts and how many coils need doing. This job was $680 for an OEM coil set including labour, done the same day.

The choice that moved the price here was original versus OEM. The original set was quoted at $850. The OEM set was $680 and made to the same specification. For a car with only a few months left before scrap, the OEM option made sense. For a car you plan to keep for years, original parts can be the better long-term choice. Either way, we quote both and let you decide.
