Engine Mechanical problem
2000 Chevy Malibu 6 cyl Two Wheel Drive Automatic 156000 miles
My car is making a knocking noise. It's loud when idling but it gets quieter as I accelerate. The other day I was driving and it just died on me. Now it wont start over. It starts over once in a while and backfires a couple times and then dies. My brother said that it may be the timing chain? Do you have any ideas what it may be?
