I have a 2004 electra glide that's sputtering

If you haven't done a tune up in a while, I would do the Plugs, Filters, Oil at the least.
You may see something, or it can only help.
Sit for a while?

Put new fuel filter intake gaskets.. injectors and temp sensor problem is intermintent

I would check connections on sensor, if OK, then I would replace.
How did the plugs look?
