Just filled back up with 91 octane two days ago and oar will not climb back up to -1.00 its been stuck at .032 for the last 60 or so miles,How do you determine if this is low speed ignition knock,ie spark plugs possibbly,or that its bad fuel.Running the oem tune stage 0.Cylinder 4 correction has been as high as 2.5.
Now I have been running 91 mixed with e85 to make e20 e25 and for the added octane values for the last couple of months is the system trying to reset it self for the 91 octane and if so how long should this take?,.Motor has 26 thousand with the original plugs as well,maybe time for a better and new plug change? Thanks for any info
