The good thing is I fixed it as of right now; I’ll check on it again tomorrow...
So out of nowhere today, while I went to a shopping center about 20 miles away of my place of living, the car started to act strangely; sudden vibration of engine; at first I thought about someone messed my car while I was away but nothing unusual I noticed; meanwhile the sky opened, rain; I moved inside the car and I’ve noticed the engine light was on; I have the OBD scanner but it was at my home 20 miles away; the car was experiencing vibration and was shaking significantly and while it runs right at low speeds, once you reach up to speed it sounds much better; on my way home via interstate I've noticed inconsistency of the check light, while flashing one time, others time is solid; on my way back I stopped to the Advance and they scanned it for the codes; there were three codes P0304, P0171, P2274 so that 4th cylinder was misfiring; from that point I was suggested to step by step elimination process; and that’s what I did;
I swap the coils between the spark plug and no improvement; I want back to the Advance while they were still open, this was at 7:30pm and I got me Denso spark plugs; I replaced them; then there was a change, the car went back to normal; however I found of traces
So tomorrow I’ll watch for the check engine light, and I hope I’ll go back to work in my Mazda; I need my Mazda not gave up on me also if anyone knows more about spark plugs I wanted to see your opinion and what do you say the condition my engine in Mazda
