I have a 1999 Honda Accord EX that has a V tech engine and it does NOT
produce nasty black smoke from the exhaust system. Therefore, I think that
your dealer is lying to you. The next time that you visit the dealer, ask
him to stand behind one of the new or used Honda cars on the lot. Start it
up while watching the rear view mirrow. After NO black smoke comes out,
ask him why it comes out your exhaust pipe and not the exhaust pipe on the
one you just started. Back to your problem--there are several possible
causes. The best place to start is a complete tune-up. If that does not
solve the problem, run a compression check on each cylinder. Please repost
after you have done those things and let us know the results.
