Title capitalization rules

The strange noise ishad disapperdared, so iI was very happy. The strange noise had disappeared, so I was very happy.

Sequence of events, first the noise "had disappeared" and then your reaction "I was." To use present tense (which you can do here): "The strange noise is gone, so I am very happy"

During aWhile heading to home i, I stopped at a market and bought some matcha tea. While heading home, I stopped at a market and bought some matcha tea.

If you want to avoid repeating "heading home," some alternatives: Driving home Going home On my way home

I am going to taste itdrink/try int today, so I am very exicited about it. I am going to drink/try it today, so I am very excited about it.

"Taste" implies brevity, and does not necessarily mean you will eat or drink the thing in question. "Try" would be a good substitute if this is a new food/drink to you and you intend to drink/eat all of it (assuming you like it). Otherwise, the default "drink" works

As iI mentioned in my last text, iI had a car problem so iI took my car to a mechanic and he fixed it. As I mentioned in my last text, I had a car problem so I took my car to a mechanic and he fixed it.

"I" is always capitalized

Yesterday i, I picked up the car from the mechanicer (after a heading to homeI had headed home during the repair). Yesterday, I picked up the car from the mechanic (after I had headed home during the repair).

Sequence of events, first you went home (had headed), then you picked up the car. Added "during the repair" so the reader has more context. However, I would just omit this section in parentheses from the sentence.
