Just send your injectors in to be cleaned and flow matched. There is absolutely nothing you can do that will equal a real cleaning.

 

Real cleaning = Best

Though when I change my fuel filter, I fill it with seafoam when I put it back in.
My $.02...

Or throw a couple of cans in the tank when your fuel light comes on. (Have a can of gas with you!) Run it for a bit and fill.

 

I'll run a very concentrated mix of seafoam/fuel. Too much Seafoam and you'll throw a code. Ask me how I know this.

 

OK how do you know that?

Nah just messing.

I put some seafoam into my 98 tacoma to fix an irregular idle where i used 1/3 a can into the intake and 2/3 into my fuel tank when it was at less then 1/8 tank left and after i drove it 2 miles to the gas station and filled her up again then drove around for 15miles my truck got back to its normal idle and the check engine light i had on for the past 3 months finally turned off.

Like a few have said its best to just send them to get cleaned professionally instead of going through all the trouble of trying a set up like you mentioned.
