When to Replace
Signs of dirty, clogged or malfunctioning fuel injectors include:
- Engine misfiring or rough idle
- Hard starting or a no start
- RPM needle bouncing or engine surging
- Poor performance or increased fuel consumption
It can be difficult to diagnose fuel injectors on your own, so you may want to have a local shop test them.
