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
The DENSO spark plugs are 6 for $23 at walmart. These get great fuel economy , smooth idle, Great Power.
Pros: great fuel economy
These are good plugs Autolite my mechanic recommended them to me good spark and seems like my truck is running smoothly and there a good price.
Pros: good spark, running smoothly
Apart from that, NGK is my go-to brand for everything they make.
Pros: go-to brand

I noticed a slight miss at while cruising between 67 and 70mph. I ran VCDS logs and found misfires on cylinders 3 and 4. Imagine my surprise when I pulled the plug for cylinder 3… no signs of any other damage and I have no idea how long it’s been like this. Never got a CEL.
I installed the new NGK Ruthenium HX plugs and so far everything has been great ????
Pros: everything has been great
Cons: slight miss, misfires
Mileage: 20000 km
2018 Kia Soul Base, 57k miles, on the third set of plugs and they are misfiring already. Factory plugs lasted 30k miles, followed up with Autolite plugs lasting 10k (which I chalked up to being cheap/low-quality plugs), but now these NGK iridiums are giving out with 17k miles on them.
Pros: iridiums giving out
Cons: misfiring already
Vehicle:
Kia Soul
Mileage: 91735 km
Avoid Champions. Use NGK or Denso. Don't go cheap on plugs because the job is labour intensive.
Cons: Avoid Champions
