Clean injectors
I typically use Seafoam...stuff has done a solid job for me in the past as a gas treatment and in vacuum line.
Although i will say, never pour the stuff in the crankcase if the engine is old. Blew a headgasket one time that way -- kinda like using diesel gas to flush things out...great idea if everything is cherry...but it can open up that can of worms.
anyways, Seafoam has gone way up in price and i had some extra NAPTHA laying around.
Worked awesome. I poured about 4 tide detergent cups worth into my vacuum lines the other day and it worked great.
It's a dry clean though and this was on a 4.9L.
anyways, thought i'd pass that obvious info on.
Never tried using electricity to clean the lines / injectors but i've heard of that

I think many of us car folk are cautious by nature when it comes to our vehicles but truth be told, if you drive your vehicle enough you should not NEED to clean your injectors.
If you drive it, and it's got semidecent gas in it, they shouldn't be a problem.
Hell, my truck has six junkyard injectors in it. The inspection on the truck I pulled them from was 2 years old. Who knows how long it was in the yard. I Seafoamed the truck the first time I started it. 2/3s in the tank, 1/3 in vacuum line.
It smoked slightly as I poured it in the vacuum line, but didn't smoke at all when I turned the truck back on after letting it sit. I was kinda...suprised. Must be clean inside haha. My Supra gonna get seafoam too, but that's down for the count for now.

I wanted to do Seafoam because my truck has some black sooty smoke when I stomp on it. I didn't know where to find the vacuum line I was supposed to use so I put it in the tank. I didn't notice any change at all.

Craig,
You can add it through the vacuum line to the brake booster.
Run rig to op. temp.
While idling, add seafoam to vac line,
Shut down and add rest to tank.
Start up after 20-30 minutes or so.
