Misfires are where parts-cannon mechanics lose customers — swapping plugs, then coils, then injectors, hoping. Drova reads live cylinder-balance and misfire-counter data from the ECU to find the exact cylinder and the exact cause, then quotes the right fix.
A misfire can be a coil pack, spark plug, injector, leaking inlet, weak compression, ignition wiring or even a bad earth. The car doesn't know — but the ECU does, and the live data tells us. That's how a £40 plug doesn't become £400 of guessed parts.
A flashing engine light during a misfire is serious — unburnt fuel destroys the catalytic converter. Drova fits Drova into your day at home or work, fast.
Diagnostic £69 · Plugs & coils from £140 fitted. Injectors and inlet work quoted after diagnostic. Drova never quotes blind on a misfire.
Almost always a misfire — one or more cylinders aren't firing under load. Most common cause is a coil pack or spark plug on petrol engines, an injector on diesels. Live data tells us which cylinder in 10 minutes.
Active misfire severe enough to damage the catalytic converter. Stop driving — every mile costs cat life (£600+ to replace). Book a same-day visit.
Not necessarily. If diagnostics shows one specific coil failed and others are healthy, replace the one. If multiple are weak on a high-mileage engine, the full set makes economic sense. We'll tell you honestly.
Low-rpm misfire that goes away under load — classic vacuum leak, dirty throttle body or carbon on valves on direct-injection engines. Diagnosable on the visit.
Yes — over time, yes. Short-term it kills the catalytic converter (unburnt fuel burns the precious metals). Long-term it can wash cylinder walls and dilute the oil. Don't ignore.
£69 diagnostic call-out, comes off the repair if you go ahead the same day. Plugs and coils typically from £140 fitted; we never quote blind on a misfire.
