My 2001 chevy cavalier started sputering and wouldnt pick up speed I just had the oil changed. It was not doing this before I took it in. when I left it had a hard time starting. Then when it did try and pickup speed it seemed to be catching then a loud noise with jerking then it dies. Anyone know what may be causing this

SOURCE: How do you change the headlight for a 2001 chevy cavalier

i actually just did this a couple days ago, this takes about 20 minutes and a little bit of patience. When you pop your hood you will see a protective piece of plastic over the headlights/radiator, you firstly have to remove the plastic clips holding that piece then pull that piece of plastic off, once done u will see 2 bolts holding each headlight in place, i believe it is a 9/16 socket but if not just find the one that fits, remove the 4 bolts (2 for each headlight) and pull the headlight in an up and outwards manor. if you feel any resistance do not yank look at why it is catching and clear it, then it should just pop out (the headlight and the corner piece and clipped together so dont pull it too far out) then when the bulb is accessible pull the old bulb, put the new bulb in and voila place the headlight back into position, redo the 4 bolts holding the headlights and re-attach the plastic headlight/radiator cover. Enjoy the new lights

If new bulbs don't work, it is probably the harness that holds the bulb. I had to replace both on my car after fighting with the problem for over a year and not knowing.
