hi today on the way home from work my car jerked alittle while
accelerating. i thought nothing of it so kept driving. when i almost
got home the car jerked again when i acclerate and the check engine
light came on flashing. b/4 when check engine comes on it didn't flash
but this time it did. i know all about the loose gas cap but i don't
think that's the issue. what kind of damage am i looking at and around
how much it will cost this fix it? my can has 106k miles on it....
TIA
