Default Cleaning Injectors: Is Seafoam more effective added to gas or through vacuum hose?
Have a rough idle and a misfire. Put new plugs in and am awaiting some wires. But i suspect my injectors might be clogged. I would assume adding seafoam through the brake booster vacuum hose is better than adding it to the gas, in terms of how effectively it cleans the injectors, but want to get some other opinions from those who probably know more than me. TIA.

Umm, running Seafoam thru the vacuum line can't clean the injectors

Default Instructions indicate either adding to oil, gas, or via vacuum hose....
that feeds all cylinders.

Default gotta put it in the gas in order for it to go THRU the injectors...
cleaner specifically for injectors may work better.

Default The trick is full can in the fuel, half can thru vacuum line, rest of can in oil.
Drive the car 50 miles, change oil.

50 miles to get it through the fuel lines, 5 minutes idle maybe if only doing the vacuum, and oil.
