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. -James
