My 2005 Pathfinder Se Off Road, is giving me a service engine light. Had it checked and was told that I had a carbine problem. So talk to a mech. and he suggested using a fuel system cleaner, I did this at my next fill up. It cleared the light but if I fill up in between treatments the light comes back on. The treatments should or should not be used every fill up? Is there anyone with any suggestions? Or should I just put it in the shop and let them deal with it? The Pathfinder has no problems running, but mpg`s are bad when light is on.
Thanks for any reply.
