replaced both knock sensors, harness, plugs and wires. Checked ohms 100.2 from each sensor, checked harness to pcm including wiggle test continuity good. No knock, drives well, monitored misfires its only on 1-5-6-8 and only in park, if you goto drive and stall test it at all the misfire count drops to 0. swapped coils and inj on 1 and 3, misfire stayed on 1 didn't move to 3. Seems as though the p0327 controls 1-5-6-8? any thoughts

 

Two separate problems, replaced the front knock sensor again, code gone. Aftermarket sensors the problem???

p0300 code caused by slacked timing chain, correlation was off setting a misfire code. performed crank sensor relearn, p0300 gone.

 

Did replacing the knock sensor fix your p0300 miss fire issue?. My truck just all of a sudden started running really bad. No power and missing and back firing.. check codes and i have both the p0327 for knock sensor and a p0300 miss fire. Thanks for and help you can give me
