Hi,

I have a 1998 Accord V6, and have recently got the "Check Engine
Light". Since I have the OBD II decoder, I got the code out, and found
that it is P0401 - EGR Flow Insufficient". From a little research on
google, found that this might be a known Honda Issue (TSB-99-085) and
Honda has a recall on this. Since my Accord has 110,000 miles on it, I
will not be able to get a free service from the dealer.

Having described the problem above, I would like to get the service
performed myself. I read the TSB from honda, and the procedure seemed
simple. Basically cleaning of the EGR port in the intake manifold is
required. Of course Honda also suggests that the EGR port on the intake
manifold to be drilled with a "special drill" to make the hole bigger
and insert some kind of "tube" that comes with the kit that is
available at Honda dealer. The kit itself is around $80.

My question is, is it worthwhile to get the kit and do all this
drilling business or just replace the entire intake manifold ($160 -
Honda OEM from dealer) ? Will the new Manifold have the bigger EGR port
as Honda knows about this problem in the year 2000 and would have
corrected the EGR ports on the new parts ?

I have these three questions for the group :

1. Is it a good idea to replace the entire intake manifold  ($80)?
2. Get the kit from Honda and attempt to repair and "clean" the inake
manifold ($160) ?
3. Get the service done at the dealer ? ($350)

Thanks,
- John
