I am getting trouble codes 440, 300, 301. Will not pass inspection due to these codes. Spark plugs have been replaced recently with correct spacing. Hoses from the EVAP canister were found to be dry rotted and were replaced. 440 came up after the hoses were fixed. The engine does not run rough, but does idle at about 500 RPM. Help me pass inspection!

Let it sit for at least 4 to 5 hr or over night
replace coil
reset codes
start engine let it idle for 5 min
take it for a 5 to 8 miles drive
do not shut off the engine

check monitors if ready
you can pass if have one not ready
if have two or more monitors not ready, take it for another ride
as long as you dont have the check engine light on
good luck
