As the weather has gotten colder, my titans ticking seems to have gotten louder. Is this still just the injectors ticking away or could there be something more to it? I can hear it in the cabin(softly) when the A/C and radio are off. Only noticeable when idling or coasting in a parking lot etc.
One other symptom that I doubt is related, when i go to accelerate from a stop, right as the throttle hits load, there is a rattle(?) type sound just for a beif second as it starts to pull. Sounds like its coming from the bottom of the engine area.
