Alright here it is again, i have a B16 in my DA and it was running fine, then it wouldnt go over 25mph one day and it wasnt driving well at all... so i changed the temp sensor on the head.. and it still feels like im pulling a load, the car just doesnt want to move although it does go over 25 now when vtec engages it feels like i hit a wall and it just dies.. i have changed the distrib the ecu, the map sensor, obviously the temp sensor checked the knock sensor, the car is throwing no codes at all either.. Does anyone have any ideas or suggestions??? im bout to part the car out.. its been 3 months now..
