hey got a question for you guys. so i am working on a vt365 for an internaitonal School bus. the main problem it came in was excessive white smoke out the tail pipe. after i daignosed it i found number 2 injector to have cracked across the tip letting fuel in at all times. so i decided to go ahead and replace all the injectors. after i replaced the injectors the bus now wont acell past 1500rpms. like a no power issue. i have cleaned the egr valve and cleaned the turbo for cokeing. i replaced the exhaust back pressure sensor and cleaned the tube. i replaced the air intake temp sensor and the map and temp sensor in the intake too. i replaced the air filter also. i am at a lost and dont know what could be. my vgt is operating on service max i am getting proper ICP pressure. any ideas?
