My car wont start sometimes, its totally random like it will run for a week and then one day it wont start. The 1st mechanic i took it too couldn't figure it out. the engine will crank but not all the way over so its not the battery and i have new cap and rotor, new spark plugs, new main relay, new ignitor, so its been at acura ll week and their still tryin to figure it out. anybody have any ideas?
