Tuned maintenance
For anyone looking for the 6509 1 step colder. I just looked on Amazon and they are now 3.23 per plug.
Yep, my car has had them since it was new. I made a thread a long time ago here. https://www.cobaltss.net/forums/2-0l-lnf-performance-tech-153/low-rpm-bucking-misfire-no-dtc-134963/
Tha car bucks sometimes under moderate loads and low rpms. It did it really bad for the first 5-6K miles It has gotten better now that I tuned the car. It still shows a few misfires here and there but they are not as bad because I cannot feel them happening like I used to.
You should see how many misfires and how much part throttle knock Reign1s car has on the stock tune and 91 octane.
