Basically any line that will put the seafoam though the tbi should clean up those injectors

 

i just got done doing the seafoam thru my truck i put it in the gas not much maybe 2 shot glass amounts
then i took off my hose that goes to my pcv valve and let it suck it up into the tbi and intake

i let it run it idled down and died soon after then i waited a little bit and started it back up and ran it it didnt smoke at all so i feel like im doing something wrong or ive got the cleanest engine ever made
no smoke at all like there should have

and i checked the spray again after doing this and it was still the same as before
but it does run alot smother know didnt die out when i was in park or turning a corner or brakeing


but i really do feel like i did something wrong cause there was absolutly no blue smoke the normal kind whne you run seafoam thru it
