EXPERT PETROL INJECTOR TESTING & CLEANING
Smooth acceleration, stable idle and good fuel economy all rely on healthy petrol injectors. Over time, injectors can suffer from internal deposits, uneven spray patterns or reduced flow, which can lead to misfires, hesitation, flat spots and increased fuel use. Even a small imbalance in flow between injectors can noticeably affect performance and drivability.
Our professional testing and ultrasonic cleaning service helps identify these issues and restore consistent, efficient engine operation. By checking spray pattern, fuel delivery and response, we can show you exactly how each injector is performing and what improvement has been made after cleaning. This gives you clearer insight into your engine’s condition and helps prevent unnecessary parts replacement.
