My car is chugging


Starting yesterday, on my way to work, my car started chugging about 1 mile from my office. I had about a quarter of a tank of gas, but I added more just in case. My car was fine on the way home. Now, this morning, it started chugging again on my way to work, to the point that I had to pull over I was so nervous.


Make, model, year, miles, are all the regular maintenance items up to date, What has the repair history been ???
