car is missing when driving slight jerks, after driving for awhile it wont start

Frist step is to see if there is any code, repair that first, if no code we need to check the motor for the miss, is it the plug, wires, fuel injector, or the motor its self? then fix that repair, if this is too much for you, we would be glad to look at the car for you, we charge $89.95 so give us a call
