ALL iac valves are made VERY STURDY and are easily cleaned up with SOLVENT a CHEAPER repair. Do NOT forget to clean the BACK of the plate on your THROTTLE BODY! I use AMSOIL POWER FOAM fo r this, and it works GREAT! Then GUMOUT as a chaser. GO to ANY HONDA dealer for that replacement HOSE and even the PCV Valve. The ORIGINAL FACTORY equipment on NON DOMESTIC cars is the best for you. THe cheaper rubber used from AUTO PARTS stores is a LOSER and another waste of money They are TOO thin and will collapse even SOONER! power wash YOur ENGINE TO SPOT ANY OTHER LEAKS WITH ENGINE running USING gunk orange AND BE clever ABOUT IT. fOCUS THE HIGH PRESSURE WATER away FROM THE DISTRIBUTOR IF YOU HAVE ONE. i BELIEVE THAT YOUR honda HAS INDIVIDUAL coil OVER plugs TECHNOLOGY THAT WILL not BE DISTURBED EASILY FROM high PRESSURE CLEANING. keep the engine running AS YOU DO THIS. USE only the IRIDIUM or twin tip DENSO tech spark plugs in there. It burns MORE fuel MORE completely for best power and such. GOOD LUCK!!
