I removed my egr yesterday because I got some free headers for my ka24de, I used the isis block off plate and i followed a diy online. Everything was done right no leaks form the egr 1 little pipe in the back i capped and the other two already had a tube circulating. I got a brand new o2 sensor and i ran my codes and i get nothing wrong just an old auto tranny code now im 5 speed. What is can be going wrong?!?!!? sometimes it works fine other times it bogs at 3k rpm and dies at a light if i dont press on the gas. This morning I took it out for a drive it drove fairly good all of sudden it began to bog even at open throttle now the car wont even turn on! Help a brother out guys im a full time college student I dont have the money to take it to a shop. Can someone please point me in the right direction! Im super frustrated!!
