When idle, I have noticed my rpm drop slightly and go back up to where it was. I can feel the [engine](/topics-engine-chrysler/) going as well, lightly Mechanic's Assistant: How many miles are on the car? What size is the engine? 130,000 and a v6 Mechanic's Assistant: What is the make/model/year of your car? Chrysler(###) ###-#### Mechanic's Assistant: Are you fixing your Chrysler [200](/topics-200/) yourself? What have you tried so far? So far all I have done was pour fuel injector cleaner into the tank on two occasions Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? I had a misfire that caused the check engine light to blink. It turned off after blinking. This made me buy the injector cleaner. It has not happened again since that one time.

OK since the engine light came on and was flashing that is telling you its a misfire and the cause is usually a bad coil .I would change the plugs and find which cylinder was misfiring as a code will still be stored like p0301 . Once this is fixed it will take care of the issue. If you need more help please use the reply tab to continue our conversation.
