Nissan Altima keeps dying, now wont start: started off acting like it would die at stop signs. Then eventually died and wouldnt start.
Car plugs were changed and it started right up, but after 3 days started doing it again. Took to mechanic who said it was exhaust: changed muffler and took off resonater, but 2 days later started doing it again and now it is sitting and wont start. Any suggestions?
