timing Chain replacement

FIRST more important question ....WHY????? It does have a chain , which usually does not need replaced under normal conditions until at least 200K miles or more. DEPENDING on the competency/experience of person performing the work , and the quality of parts used (OEM is BEST) , figure 3.5-5 hours of labor (your local labor rate) and IF the repairs are done as recommended by Honda , the car should sit overnight before running , to prevent leaks from the new sealant at case cover.

belt/chain same thing basically, spray some soap water around and check for vacuum leaks then my next step would be ignition module/coil check then tps and check egr by a quick disconnect of wires to see of any changes
