AR97Pathfinder Posted October 28, 2020 Share Posted October 28, 2020 Is using the sea foam spray through the intake as well as some through the line that feeds the IACV a safe and good method to clean them out? Is it okay for a vehicle with this age and 180,000 miles? I’ve seen people do it on the pathys and qx4s. If so do you feed through the brake booster line as well or through the throttle body boot. I know you get a lot of smoke afterwards. And should you perform an oil change right after? Link to comment Share on other sites More sharing options...
