misfiring

Hi, There are many possible causes for this problem. There are couple things you should know that to make the engine running you need air, spark, gas and exhaust gas leaving the engine. Sounds like the problem is intermitant. In your case it is very difficult to help you online without proper powertrain management diagnostics. You should take your car to a mechanic and have it properly diagnosed. If you live somewhere in Charlotte, come visit my shop and I'll try to help you out or give me a call.
