Spark Plugs & Ignition Coils — Cranbourne West
Misfiring, flashing engine light, or fuel economy quietly getting worse? Ignition faults are common, cheap to diagnose and expensive to ignore — a misfire can destroy a catalytic converter.

Pick a day below and we’ll confirm your exact drop-off time by SMS. Real Google reviews from local drivers.
Signs you need this looked at
- Engine shaking or stumbling, especially at idle or under load
- Check-engine light on, or flashing (a flashing light means stop driving)
- Hard starting, or hesitation when accelerating
- Fuel consumption creeping up
- Rough running that gets worse in the wet
Diagnose first, fix second — quoted before either
- Diagnostic scan to identify the misfiring cylinder, rather than replacing all the parts and hoping
- Coil, plug, lead and injector testing to find which component is actually at fault
- Correct-specification plugs fitted and gapped, and coils replaced where testing proves it
- A post-repair scan and road test to confirm the misfire is genuinely gone
A misfire dumps unburnt fuel into the exhaust. Left running, it can take out a catalytic converter costing many times the ignition repair. Where the fault isn’t obvious, we book it in for diagnostics (from $374, two-hour minimum, charged for our time) — then the repair itself is quoted in writing before anything is replaced.
Spark Plugs & Coils — FAQ
It depends what the testing finds, so we won’t invent a number. You get a fixed written quote before any repair work begins. Where diagnosis is needed first, that is from $374 (two-hour minimum) and is charged for our time, not offered as a free quote.
We can tell you the likely causes and what testing is involved — but a phone diagnosis is a guess, and guesses get the wrong parts replaced. Call 03 8782 0711 and we’ll tell you straight what’s needed.
It depends on the symptom — some of these are merely inconvenient, others are genuinely unsafe. Call and describe it; if it needs to stop being driven, we’ll say so rather than book you in next week.
