When in park or drive when stopped, you can feel it lunging forward about every 10 seconds . Just did an oil change with full synthetic oil and changed the spark plugs. Also put a bottle of Lucas gas treatment in about a week ago. It has 120k miles, inline 6 engine. I just bought this Jeep about 2 weeks ago. I did not notice the Jeep doing this before I did the work listed above. I don't know much about Jeeps, this is my first one. Can somebody please help me find an answer to this problem?
