Engine Mechanical problem
2000 Ford Focus 4 cyl Two Wheel Drive Automatic 145000 miles
Have had this problem for a year car runs but now when I drive it is fine but when I stop or idle for short period of time it basically sounds like its going to die. So went to get the code read problem is I already changed it once before and check engine light came on 1 day after so what could cause the O2 sensor to go bad would I also need to change the catalyic coneverter this nvr happened until I got bad gas at a gas station 1 yr ago.
