My check engine light came on a while back when i first purchased this vehicle. The mechanic said that it was a faulty sensor and replaced it. It has not come on again until just a few days ago. Now, it drops RPM's and when it down shifts, it shifts hard and makes the whole vehicle jerk. I have changed the oil recently and it is due for a tune-up. Do you think that a tune up will fix it or do i need to take it back to the dealership for them to look at? It has a 2 yr bumper to bumper warrenty. Thank you so much!!
