The fuel injector on cylinder 1 has a circuit fault. It may not be firing.
The engine is misfiring across multiple cylinders. This is often caused by something that affects all cylinders — spark plugs, fuel quality, vacuum leak, or low compression.
The engine is running lean on bank 1 — too much air or not enough fuel. The ECM has maxed out its fuel trim trying to compensate. Common causes include vacuum leaks and dirty MAF sensors.
Frequently Asked Questions
- How do I know which injector is bad?
- If P0200 appears alone, unplug injectors one at a time — the one that does not change idle when unplugged is the dead one.
- Are fuel injectors expensive?
- Individual injectors cost $40-$150 depending on vehicle. Cleaning may fix some issues for $15-$30 with fuel injector cleaner.
