Thanks for asking your question. I will try and help you out.

You most likely have a faulty injector. If the temp is low and there is a miss, most often I find the injector is faulty. To confirm you would just need to have a cylinder cutout test ran.

There is a chance there's a cylinder problem like a valve not sealing or cylinder wear but most often this is not the case.

I would have a cutout test ran to verify.

Please reply back if you need more help or have more questions. I am happy to assist.
