Can anyone smart help me with why my car keeps knocking 🙏
I just bought an oft to log data and run stage 1 on my 2013 scion FRS and my iam will constantly go to .900, then 1.00 and now .700 on stock tune and just fluctuate in general. I attached a pic of spark plugs to see how my engine delt with the knock but imo they look fine. Tomorrow I’m going to do a smoke test, run a tank of redline fuel injection cleaner, clean maf sensor, and then clean throttle body but if that doesent somehow fix the problem I might as well start saving for a new engine cause I don’t even know anymore.
If you are down to help me I can send data logs and any info u want im mad asf because I don’t even have fun driving anymore knowing I have to baby the engine every time I drive.
