I run a genesis, and I read that the correct temp range for the engine is between 240 and 250 F.
I was ideling the truck today and had a temp of 305 F. If I were running to lean on the bottom end would this cause my temp problem? I know running to lean on the top end takes the temps up. Im trying to find that happy median and idel so my truck idels smooth and doesnt lurch forward. Any suggestions?

Thanks AZ_JAY
