Okay so its a v6 3.8l auto 2001 mustang. All at once seemed to lose power and noticed it was like 3 qts of oil low and the AC stopped working that day too. Literally all in one day. Anyways read codes at auto zone had a "mechanic" chk it out and cylinder 1and5 had no spark. Replaced coil pack and 6 dbl plat sparks and still the same. Maybe worse. No spark from the same two cyl and the car won't hardly go without it being on a downhill. Very loud and jumpy. Ideling bad. The works. Has anyone else ever had this prob?
