what could cause my car to run one day then shut off and not start for days, weeks and then just start
the check eng light is on last time I checked it was purge valve I replaced one of the valves on the cluster the other two had diff. plugs I thought i fixed it because it started and the light went out but the next day I started it and tried to drive it and it start rough and died as soon as I drove down the lane and wouldnt start. so I pulled a plug wire and stuck a plug on to check for a spark( i dont have a real tester) and nothing i tried two diff wires. plugged it back in and tried it again just to see and it started but I dont think it will stay running and the check enj light is bac on again.... what should I do now?
