Just throwing it out there, there is a correction to the 2003-2005 manual that swaps the codes listed in the book, thus making a 26 the left and a 25 the right. I was getting a 25 for awhile too, but since the fuel pump issue was fixed, I haven't had it come back on. Bought two knock sensors just in case I needed to swap one or both, but so far they remain on the shelf. Never have touched the ECU.

YMMV.

The vacuum lines and 5 way tee are under the gas tank cover (right where you put the gas in). Under the tank cover is a large, black plastic lid/cover that houses the air filter. Once you remove that you’ll see the tee and vacuum lines. It’s not difficult at all to get to. You can be in there in 10 minutes or less. Good luck and let us know how you make out.
