This episode is a slightly different to our normal track day style videos. A common problem on Clios are injectors failing and being typically hard to diagnose. We run through five different techniques to help identify which one to replace.

Often you'll find an injector gone after your car has been parked up for a while. This set of injectors were fine, taken off the car for a few months and upon reinstalling them 1 failed. The might show their face by an engine management light. I noticed the EML flashing once or twice in a couple of months of use so was very surprised to see the effect it was having on the sparkplugs.

For Clio 172/182s the injector resistance should be around 14.7 ohms but they usually come in at a marginally lower reading.

As I say in the video, these techniques can be used on most petrol engine cars but do use common sense, not all will be practical on all cars. Diesel injectors work at extreme pressures and have a totally different testing process.
