Failed emissions What do I do car has not been used in a while

Go local mech

(Driving cycle) Can be very difficult depending on the manufacturer, We; "Check Engine Pro" Recommend that the vehicle drives 20 miles distance or more per day for 5 days consecutive. If that doesn't work we recommend go to the dealer and have them Re-flash the ECU, do an update or take care of the problem, some brand name like Jeep, Hyundai, Toyota's and others have the Primary Fuel Monitor not Ready in those case let the dealers handle. Most of the time the repairs cost is cover by tge warranty.

If you have trouble codes you'll have to find out what parts it represents and make repairs. Than you'll have to drive it for until you complete your drive cycle

Reapply and go with another car
