Improve sluggish acceleration and hesitation


I have a Honda Accord EX 4 cyl. 2002. It has sluggish acceleration and hesitation problems. I put in new plugs and that improved it some. My mechanic says I should pay him to clean the fuel injectors. What will work best? What needs to be cleaned? Would new plug wires help? Gumout? Big differences in cost,

Advice from experience would be much appreciated - thanks.


More information, such as when oil changes, air filter and gas filter were done last, Miles and any engine lights?

I do regular oil changes every 3-4 K miles. I recently changed the air filter. No engine lights are coming on. What else?
