Q: Car shuddering and stalling

asked by on February 04, 2017

Hi, my boyfriends car is shuddering and stalling when at low speed/revs. He replaced the fuel injectors about a week ago and the car started running fine. He has been running the car with about a quarter tank of fuel. Today he filled the tank to full and the car started shuddering and stalling again. It also emits a fume smell. Any ideas?
My car has a manual transmission.
