You should take your car right back to the repair shop, because they didn't fix your problem. After a check engine light repair, the light should not come back on. You may want to get them to tell you what code is causing the light now.

Try replacing cylinder 3 COIL PACK first! About $180.00 -- I have had this problem also in the past. If than your engine light is still on. Have the codes re-read after they have been CLEARED after relacing cylinder 3 Coil Pack. Let me know if this helped
