I have read about all the problems with the egr valve and the cpi on this site. I am having problems of rough idle and missing at idle. Take off is sluggish with the miss. There is no engine warning lights on at this time. Highway speeds not bad and passing is fine. I was wondering about the egr first, I was going to take it off and clean it for carbon. What I am wondering is, has anyone just blocked off the egr with the gasket and metal plate, like we used to in the 80's? Just leaving the egr off. If so how did it run without the darn egr. I want to know cause i am thinking of trying this.
