Hello and welcome to Just Answer!
I would not worry about driving your car with the light on! If the car is working the same as before and the MIL is not flashing it will be ok to drive it. You likely just have an emission fault code from the gas cap being loose.
I would take your car to a parts store like Autozone etc and have them read the code for you. Some places will do this free of charge, so just phone your local Autozone or parts store and see if they will do that. I would like to know what the P code is, so I can help you determin the cause. Let me know, thanks!
Hello, Fault code P0300 is a multiple cylinder misfire code. It sets when you have multiple cylinders that are misfiring. This could be caused by numerous things like ignition system, fuel system or engine mechanical problems. When the misfire gets bad enough it will start to flash the MIL(malfunction indicator lamp) to warn you that it could damgae your catalytic converters.
Did the mil ever flash?
How does the car seem to run now, does it shake and run rough more than normal?
I will reply back to you on my next break, thanks!
If you haven't had a tune-up in awhile I would definately start there. I would replace the spark plugs, clean the fuel injectors and decarbonize the engine and then you will have to just drive it and see iff that fixes it. I have had it where this happens after filling up with gas, maybe you got a bad tank of fuel?? I would also add some fuel system cleaner and some gasline antifreeze to the tank to remove any water that may be in the tank.
If the check engine light comes on and it starts to flash you should not drive the car because it might damage the catalytic converters.
When you turned the key to the start position and the engine wouldn't turn over did you here any clicking noise? Let me know, thanks!
Hi, I'm sorry I didn't get back to you. I have been real busy!
The problem with the starting issue sounds like it could be related to the ignition switch, but it is hard to say without properly testing it. If it has only happened a coulpe times I would not be concerned about it especially since it started after you cycled the key.
Let me know how you make out after the tune-up! Thanks,
