I went out of town for a week and when I got back, I decided to take the car out for a drive. When I started it up and let it idle for a few minutes, I could hear it missing every so often. After driving it for a few days, the miss has gone away. What could be causing this? Should I be concerned?

 

If its gone I wouldnt worry about it

 

Plugs? Plug wires? I don't believe it's anything serious. Find a nice day and get in the driveway and go thru it.

 

That's what I was thinking, because this happens every so often. I just hope it isn't the beginning of something catastrophic! I hate when cars start showing their age[:@]

 

I know the plugs are alright and I just replaced the plug wires but I will definitely check everything again tomorrow after work.

 

i wouldnt worry about it. But you could run some fuel system cleaner through it if you want.
