Recently my car (1999 Accord 4 cyl) been acting up and I've identified the problem as the EGR system. I want to clean it out tomorrow, but I've not been able to find enough details to be comfortable with it yet. I've been surfing the web for the past couple nights.

Has anyone done this? Any advice? I've seen bits and pieces all over, but nothing that has tied it together well. I'm assuming I have to open up my intake manifold, but what do I do with all the small hoses attached to it? Are any pressurized or do they need special treatment? I've seen some people talk about messing with the fuel injectors. Do I have to worry about messing with that system?

Lots of question...sorry for the overload. Thanks for your help!

 

There is no pressure, just remove the EGR valve, after removal of EGR valve you should see a hole on the intake manifold, remove the idle air control valve bypass hoses, then remove the 5 12mm bolts that holds the intake manifold chamber and and disconnect the throttle body cables and remove the intake maniflod chamber. Then spray some throttle body cleaner into the EGR passage and use a hanger to clear up the passage.

 

Thanks speedy! I just did the clean out this afternoon- nice and easy. Wow was it packed.
