[Shotimes] OT help for friend with Maxima

[Donald Mallinson]

David,

I will suggest that to him, but wouldn't it do it most if 
not all of the time?  This problem is very intermittent and 
did not do it in an extensive test drive the other night.  I 
guess the chuncks could be rattling around and some times 
bounce into a position to plug the system?

As for exhaust. he has ditched the exhaust after the cats, 
so it is real loud and I am not even sure if he still has 
the converters on it, but I would guess he does.

Thanks for the thought, I will pass that along to him.
