Hello all,
I have a question for anyone that might know the answer. How do you clean the EGR ports on the H22a4? I have a 97 lude and I get the codes for EGR flow insufficient, I've already ruled out the actual EGR valve. I took a look at it, and cant fgure it out, couldnt find any walkthroughs either. Its so easy on the F22's, I can clean the entire egr system in like 35 min. now....but dang I cant figure this one out...Anybody know?

Also if not Honda will do it for free under the extended emissions warranty...I'm just bored and my car is sitting in the garage....
