So I decided to I replaced my spark plugs. There was a ton of carbon build up in the first cylinder, and oil on the 2nd, 3rd and 4th spark cylinders, including the spark plugs. It’s running way smoother now but there is still some jerking but it’s not as violent as before.

Pros: running way smoother
Cons: still some jerking
Vehicle: Mazda 2

I set the new ngk's i put in to 0.27 and I feel a difference already lot less hesitation off the bottom end felt like it would almost hiccup before gaining any power with the stock plugs. now i lay into it and it just goes fairly smoothly

Pros: less hesitation, smoother acceleration

Just installed NGK 92274 in a 2021 Mazda 3. They are 'Ruthenium' instead of iridium, seems to be their newest plug available. Just don't touch the gap, it was perfect at .044. Runs great.

Pros: runs great
Vehicle: Mazda 3
Part number: 92274

Here’s a link that may be of help. Your plugs are quite fouled and even at end of life plugs should not look like that.

Cons: plugs quite fouled
Vehicle: Toyota
