1999 Pathfinder: I had the computer checked 3 times. But no code was identified that pointed to any specific problem. Each reset caused the light to go away for different periods of time. Anywhere from 2 weeks to 4 weeks. Once it even went on and off within several days on its own. Best guess was emmissions, fuel, or loose connection on something. The car runs fine with no other symptoms. The light has been on now for 2 weeks. I'll reset again, have my mecahnic look over the engine, and see what happens. My 2000 Pathfinder has run with the check engine light on since 20,000 miles I now have 149,000 miles. It started when I changed the air filter to a K&N. My local mechanic has checked it numerous times and the computer shows no problems. You may want to check the air filter. I also own a 2002 Pathfinder the check engine light came on due to the seal on the fuel cap not making a proper seal. I replaced the seal and the light reset and has not come back on in a year.
