Tundra Hybrid Misfire

Rough engine, eh? Sounds familiar. I had something similar going on with my Tundra. Check engine light was on, throttle response was terrible, and it felt like I was driving through molasses. Have you scanned the error codes? Could be a cylinder misfire, which might point to spark plugs or even an ignition coil issue. But yeah, injectors are a possibility too. Did it happen suddenly?

Yes, I did scan the error codes, and they indicate cylinder misfires across multiple cylinders. You mentioned spark plugs and ignition coils; were those components implicated in your situation, or was the fuel injector the root cause? Also, the degradation in performance was not instantaneous but rather progressive over a period of approximately one week.

Progressive, huh? Mine was more sudden, but similar symptoms. I messed around with changing the spark plugs first 'cause it's cheap and easy, but no dice. Turned out it was a dodgy fuel injector. Honestly, with it being progressive, and throwing codes for multiple cylinders, it’s probably beyond a simple fix. I'd say get it to a workshop and have them properly diagnose the fuel system. Could save you a lot of headache and prevent further damage.

I appreciate the additional insights and the recommendation to seek professional diagnostic services. Based on your experience and the escalating nature of the symptoms, I will schedule an appointment with a qualified technician to evaluate the fuel system. The workshop confirmed that the repair was a defective fuel injector, which cost me 515€.
