hydrocarbons: 3.03... pass:1.60carbon monoxide: 86.14!!! wow!... pass:15.00NOX: .90.. pass:2.50

gas cap test:passpressure test:failevap component test: fail (notcied that my charcol can was just zip tied in and the hoses werent hooked up to anything)

so this is what i have done to the car as of today stock sohc, injen intake, vatozone filter, walbro fuel pump, and custom 2.5 inch exhaust with high flow cat. all the EGR system stuff has been removed and O2 sensor was replaced about a month ago. i took the car in with the lowest octane gas. the maff was used... came off a different car. motor burns oil.

so im basically running really rich. what to do to fix that? could my timing be off?my car backfires a little, but idles perfectly so would that rule out timing?

did i **** myself by removing my egr stuff?

what parts of the car does the pressure test check?

i knew i would fail but not this bad

Did you completely eliminate the EGR Valve?

there is your answer. that's why your running rich.

also egr would affect the nox and as far as evap, try to find a diagram on the evap system and make sure eveything is hooked up right and vacuum lines are good.
