Re: Accord Egr problems
Since it runs fine until warmed up and goes bad in closed loop you are right to assume it's something feedback controlled.
But while lack of EGR can cause pinging when given lots of throttle under load (climbing hill, passing in high gear, etc) it shouldn't cause any noticeable hesitation or misfire, especially on light throttle application. And if the problem was a lean condition caused by an EGR sticking open slightly, it wouldn't idle smooth.
Still I'm not saying it wouldn't be worth a look in the EGR pipe if it's not hard to get at. I might also pull the o2 sensor(s) and check for additive fouling...that's another item that doesn't give feedback until closed loop begins...
