I remember reading another thread somewhere but could not find it regarding stock plugs being pulled and finding the gaps have increased over time. I have had some random issues lately regarding ping, timing being pulled and my methanol pumping but STFTs not increasing under load like they should. All of which circle around the issue of knock and hesitation under WOT.
I decided to pull my plugs and do an injector service (that was due anyway). I had about 14K miles on these Denso ITV22 from Tune+ purchased may of 2016. what I found was all four plugs had their gaps increased significantly and some were from either the ground pole looking like it had a little cutout or just worn away from the spark, to just plane gap increase.
Cyl #1 .033
Cyl #2 .035
Cyl #3 .035
Cyl #4 .039
The plugs were Denso ITV22 from Tune+ that were pre-gapped to like .026 to .028 I believe.
This of course was the cause of the excessive knock, mpg loss and timing corrections that also affected the operation of my methanol setup as the system kept pulling timing and reducing fueling due to knock not the methanol and it was reducing fuel even more than expected but since timing was being pulled there were no gains from the wmi.
I have since put in NGK LTR7IX-11s gapped to .028 and now everything is fine.
Anyone else experience this and was it to this level? Maybe Adam can chime in on this...
