Latitude Running Lean
Summary of the thread
A 2013 Renault Latitude is experiencing lean running, reduced power, check engine light, rough running, and jerking on acceleration. The initial suspicion is a defective injector. After considering other potential causes like vacuum leaks, spark plugs, and the catalytic converter, the issue is confirmed to be a defective injector. Replacing the injector resolves the problem, restoring the vehicle's performance.

Thanks for the quick reply. No vacuum leaks found. Spark plugs are relatively new. I haven't scoped the fuel trims yet. Did your issue resolve with injector replacement, or did you chase other culprits like the EGR valve or throttle body?

Injector replacement fixed it for me. I also considered the EGR valve, but diagnostics pointed directly to the injectors. Based on your symptoms and mileage, and the fact that you have already checked spark plugs, I'd strongly advise a proper diagnostic at a workshop.

Understood. I appreciate the confirmation. Took it to the shop, and you were right. Defective injector. 515€ later, it's running perfectly. Thanks again!

I had a similar issue with my Latitude. Same symptoms. Have you checked for vacuum leaks? Also, what's the condition of your spark plugs and catalytic converter? A clogged catalytic converter can mimic lean running symptoms. Have you monitored your fuel trims?
