ok so i went to get emissions and failed lol…(ka24e motor)0.0 hco ppm was 62 (limit 64) co% was .16 (limit .35) no ppm 1480 (limit 727)

ok so that was done when i had a leak off of the down pipe gasket so fixed that and changed mass air flow sensor or valve( the one the tubes into intake with the black plastic box ) and then went for a re-test.

hco ppm went up to 70 (limit 64) co% went up to .37 (limit .35) no ppm dropped to 1123 (limit 727)

ok so need some help in figuring this out (dont wanna pay $$160 to have it checked im a little Jewish lol…)  
or if someone knows where i can get a test done then point me in the right direction.
