New plugs, wires and 1 coil. Oh gas gage not correct reading now eather, don't know if connected or not. Thank you Kevin

If the broken belt hit the sensor and dislodged the plug it may have damaged the sensor as well, a scan may showup a faulty sensor.

Thank you for responding. I have replaced the crank sensor and it still pops when revving the motor, if u drive the car it pops when u give it gas and doesn't have the power it used to. You have to give it very little gas and it will build up speed, and get to highway speed but it is to slow to get there for the highway. If I could get the popping to go away them it would be fine to drive anywhere. Thank you
