Expert:  Wayne replied 1 month 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: replied 1 month ago.
no the only one that shold bad fire temp was number 6
Customer: replied 1 month ago.
i took shields off used temp probe
Expert:  Wayne replied 1 month 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
