Dirty injectors cause rough idle, poor economy and misfires. On-car cleaning is cheap and worth trying first, ultrasonic cleaning with flow-testing is more thorough and still far cheaper than new injectors.
💰 Ways to save
- Try cleaning before replacing, new injectors can cost hundreds each, especially diesel common-rail.
- An ultrasonic flow test shows exactly which injectors are faulty, so you only pay to fix what is wrong.
- Use good-quality fuel and the occasional injector cleaner additive to slow build-up.
