703 injector swap kills mpg?
I just swapped in a set of 703 neon injectors in my 92. I soaked them in gumout for 24 hours then put on new brings and pintle caps. I installed them and it runs very well and actually increased my midrange power but has killed my mpg. I did not reset the computer at first and I have only gone 125 miles on 3/4 tank. I just reset the computer and will see how it goes.
My question is...what else can I look for to help figure out why this huge drop occurred?
