1997 Nissan Pathfinder 6 cyl Four Wheel Drive Automatic 95000 miles
The service engine light came on and I had it diagnosed at the dealer and it gave a PO440 code. I was told that the evap canister was cracked and the canister and the control valve needed to be replaced at a cost of $496 for parts and labor. I scheduled the work to be done in a week. Today I replaced the headlights (after checking the fuses), filled up with gas and also got a car wash. The service engine light is now off! Any ideas what's going on? Should I have work done as scheduled or get another opinion?
