hey guys, been a while since i've been on here. one question about an egr failure on a 94 honda accord. well i finally sold my car 2 weeks ago to a good friend of mine. the very next day, it ran into problems. she said when accelerating when the engine was warmed up, there would be hesitation around 1800 rpm. i took it for a ride and there definitely was misfiring going on. i figured it can only be the egr doing this and i pulled the vaccum line going to it. problem fixed. now of course, with the solenoid operating but no signal that the egr is opening, its throwing a CEL. i do know that too much egr will cause misfire, and on the vacuum diagram theres something in line with between the egr and solenoid valve called a vacuum regulator or something. i'm guessing this went to shit and its letting too much egr into the manifold now. anyone ever hear of this happening or how much this part is gonna cost?
