Have 2000 accord with 175k. Shop changed EGR valve twice and engine light comes on following 10 miles of driving. Heard so tech bulletin 99-085 to clean the EGR ports. Any tips on removing the intake manifold and cleaning ports? Any other routine maintenance I should perform while intake is off?
This may seem a little basic, but just spray with carb cleaner? Any seals I need to be concerned with?
I am an old plane mechanic and pilot so this newer tech stuff is a challenge to do correctly for the layman.
