So I’ve been dealing with misfire issues for a while and I’ve replaced many things, eventually I found my compression too be low due too stuck piston rings but I managed too get them free with marvel mystery oil and now my engine has good compression again. But I still have random misfires and my idle is high until the engine warms up too operating temperature. when I was looking at the live data on my obd I noticed both bank 1 and 2 secondary o2 sensor voltages we’re fluctuating very low, generally staying below 0.1volts and I also noticed short term fuel trims in the 90% range for b1s2 and b2s2. Aside from this my other short term fuel trims were negative but less concerning sitting around -10%. I’m just wondering if this low o2 sensor voltage could be causing the issue with fuel trim and possibly the misfires or if it’s more likely a issue with my fuel injectors or MAF. Any suggestions help thanks!
