I have my 1999 Mustang gt, with diablo tune 93 oct, new iridiums plugs, accel coils and BBk Body Throttle, my question is can i use fuel injector cleaner with out no problem?
I would suggest using seafoam in the gas, however modern injectors do not typically require cleaning ever. But seafoam does not hurt I use it in my car, lawn mower, and snow blower gas tanks and gas cans to stabilize the fuel and keep the fuel delivery systems clean.
use the sefoam into the intact track via vac supply. Just be sure you do this when all your neighbors are home and perhaps on a good sunny day when they're all out doing yardwork or grilling
