Iv had a lot of fueling issues so just really want to make sure the mixture is spot on

Skippy:
i thought that i had mine right untill the weekend, but when i had it on the analyzer i was running at about 7%  :shock: , thank god i wasnt pulled over!!  The book says that mine (3.9 efi) should be at 1.0% at a 750rpm hot idle but i reached lambda 1 at about 1.5 ish and it feels alot better now too!  So in short, about there should do.
