Had my injectors cleaned a few days ago. They used a hanging canister filled with cleaner and using air pressure, forced the cleaner through the injectors with the motor running. It helped, but now I notice what appears to be two fuel lines going into the injectors I'm guessing one for each bank, and the mechanic only connected the injector clearner into one of the lines. Will the one line do all injectors or did I get only one bank done? Thanks, John
