[DML] Re: car pings when accelerating

["Dave Swingle" <swingle@xxxxxxxxxxx>]

Check your timing (with a timing light) to eliminate that, but my 
guess is that is not the issue. If all you did to fix the loose nut 
was to tighten or replace the nut, my bet would be that you still 
have an exhaust leak, just a smaller one. This will sound amazingly 
like pinging under acceleration. 

If the exhaust has been leaking at all it tends to burn away the 
gasket and burn a path into the manifold flange. You can tighten it 
all you like and it's still going to leak. The correct repair is to 
replace the gaskets AND refinish the manifold flanges.
