Well I was told my dd has a bad motor. It is a 2001 pontiac grand prix with the 3100 motor.The number 4 piston had a knock and well it is cheaper to buy a new motor than rebuild this one. So I was told. The knock goes away when the 4th spark plug is pulled. Can any one help me out? The shop I take it to said no less than 550 to 1000 just to rip it apart and diagnose it!! So should I buy a used one for 600 comes with a 3 month warranty. If so any one want to swap it out for me? I will provide food beer and cash.
