I got my oil changed on Saturday after the check oil light went on on Tuesday. It's now the following Tuesday. I got in my car this morning and it was working fine. This afternoon I get in and it hesitates to start and sputters. I try to try and eventually the check engine light comes on and it continues to sputter when the accelerater is pushed. Has anyone had this problem? Know what it is? Know how much it was to fix? Anything?
