service engine soon light...
OK, I was on a trip to the mountains when I started feeling my truck sputtering at a light. Soon after it got a little worse and the Service Engine Soon light started flashing. I looked in the manual and found out it could be either the emissions or the fuel got messed up. Well, it rained heavilly that night so I assume that I didnt close the fuel cap tight. The manual stated that the light goes on when there is water in the fuel, run out of gas or something is wrong with the emissions.
The manual stated that you should run three cycles and if anything was wrong and got fixed the light should go off. Well, the light did go off after 3 cold starts and my truck is back in full power!
My question is who has experienced the same thing and whats the deal with those O2 sensors that supposedley go out at around 90,000-120,000 miles. Should I replace them before they go out or just let them be?
By the way the light would flash when I would rev it, but would remain lit when taking it easy.

Hey 2000...
I had the same issue on mine, and it was the COP on cyl. #1. It was intermittent but got bad enough for me to have the codes read. If it happens again, go to Autozone and have them pull the codes and look them up. Mine came up as a misfire and the root cause was the COP. Hopefully it worked itself out though!
Good luck.

Don't replace the O2 sensors until one fails, then just that one. They can last a very long time. I sitll have my original right upper and lower, and left lower at 125K miles. Just replaced the upper left at 115K miles.
