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.
