Awhile back my check engine light came on and I went to Auto Zone for them to read it. They told me I had a bad spark plug. Since I had 85,000 miles on original plugs I figured this was correct and I changed out the plugs and original air filter. (I change my oil every 8-10,000 miles) The check light went off for about a day and then came back on and is still on. The car runs great and idles smoothly but has started to run rough, like on 2 out of the 3 cylinders maybe, when I first start out and have to sit in traffic at a light for a bit. When this happens I shut off the car and start it right back up and it's smooth as silk again. Is this possibly something electrical, like coils, since it is remedied so quickly by just shutting off the key and then restarting? No other apparent problems except not being able to reset the wrench symbol after changing the oil (never had this problem before either). Any help would be greatly appreciated.
