I put a od77t plug in it today and seemed to idle alot better right away. But before that the motor was shutting off down the end of the straight away at WOT. I cant remember does that usually mean you are too lean on bottom and rich on the top. Anyways is there a Nova plug that works better for hot and humid climate like a c5 or c7? Thanks for any help.
