D2 + Sea Foam = SES

Okay, I did the Sea Foam treatment, she smoked and ran like crap just like everybody else's seems to and just like my Tacoma did when I did that. However I now have an SES light on, not blinking. I'm guessing it's the O2 sensor although I have not had the codes read yet (truck has 70k with original 02 sensors). She runs fine, ran a little rough for a few miles, but once it cleared out she was quiet and smooth again. Should I just let it sit for a while and then try starting her up again to see if clears? I'm heading out on a 4,000 mile trip tomorrow, this was not in the plan

You'll be just fine dont panic. All you need to do is clear the code and it wont come back on.

Problem solved. I ended up buying a scanner and the codes it was throwing were for a misfire (multi-cylinder) and a catalyst damaging misfire. I could here the misfire after I started it up, once the sea foam cleared out it ran fine. I reset the light and it didn't come back on.

my light has come on every time i ran sea foam through the intake and that land rover fuel injector cleaner in the gas. I just ignore it and it goes away. You should be fine.

I use the Land Rover fuel injection cleaner, too, but it's never given me a problem.
