Technician: Wayne, Journeyman replied 8 months ago

My thinking is when it gets hot

operating Temp. the injectors may loose adjustment from the oil

being thinner, did you replace the injectors on the 2 bad cylinders ??

Customer reply replied 8 months ago
no the only one that shold bad fire temp was number 6
Customer reply replied 8 months ago
i took shields off used temp probe
Technician: Wayne, Journeyman replied 8 months ago

Thank you for that

That may be another issue to this also

I suggest to replace the 2 that were on bad cylinders and run the over head again

I hope this helps you
