The 'T' key on my 2014 macbook pro is behaving strangely.
It sometimes works, but often doesn't. Mostly it skips completely. Other times it has a delay, such that I type the words correctly, but the T appears out of sequence. Once in a while it will work great for a minute or less.
I don't suspect a dirty key because sometimes he 'T' will appear after I have released the key. I have cleaned under the key anyway and it looks good. I have reset NVRAM and SMC.
To illustrate the problem, here's this question as it was originally typed, before I painstakingly fixed it up.

Can I fix it?
Edit – answering questions in the comments:
Testing behaviour a bit more, I realise that many of my apps don't permit repeating (including chrome and IDEA). So I've tested in vi where repeating works. The key's behaviour seems more consistent:
- There is a delay of around 1 second before the 't' character appears and another delay of about 1 second before the repeating stops after key release. The keypress signal is delayed 1 second.
- It seems unaffected by temperature.
- As of this afternoon, the delete key is also affected.

It sounds like you have a defective keyboard. Yah it's difficult, nigh impossible, to diagnose hardware via messages on the internet but that is my guess.
It may be possible to find a used, working, keyboard on eBay or the like, if you feel up to replacing it yourself. iFixIt likely has a take apart guide that would show you how difficult it would be to do it.
If you are anywhere near an Apple Store I would make a full backup of your system. Create a new admin user for Apple to use and take it in to an Apple Store for diagnosis and/or repair.
