Honda Car Forum

Has anyone successfully performed the EGR cleaning on a '99 Accord V6
(or similar engine)? The car is misfiring between 1500-2000 rpm under
very light load, but runs fine if you stomp on the gas. Distributor
cap, rotor, wires, and plugs have all been replaced.

I had the EGR TSB performed around 50k miles under a warranty
extension/recall, but it seems that the problem has come back around
90k.

My friendly Honda Service Manager drove the car and is fairly certain
that it is an EGR problem. From google searches, it seems that the 2
most common problems are the valve sticking or the ports clogging. My
Haynes manual shows how to perform the EGR valve test, but from what I
am reading online the ports in the intake manifold should at least be
checked, if not cleaned.

Any tips, tricks, pictures, diagrams, instructions, etc. would be most
helpful and greatly appreciated!

Thanks.

Unfortunately it looks like you have to take the inlet manifold off.:-(

Perfect! Thanks. I think I will be taking it to a Honda tech I
found. This looks like job I would rather not attempt on my daily
driver.
