Titan Hard Start Cold Start Injector

I had similar hard starting symptoms with my Titan. Have you checked the cold start injector? That can cause poor running when the engine is cold.

No, I haven't specifically checked the cold start injector. Is there a straightforward way to test it, or would you recommend injector cleaning or a professional injector test?

Based on my experience, it sounds like the injection valve/injector is likely defective. Given the symptoms you describe, I'd advise against DIY repairs. It's best to take it to a workshop for a proper diagnosis and repair.

I took the Titan to a local shop, and they confirmed it was indeed the cold start injector. The repair cost came to 515€. The truck is now starting as it should. Thanks again!
