Peter:

Is interesting what you say about batery cables. The connection form negative cable to front frame memebr (only about 8-12 inches in length) is slightly corroded at the body point. We just had a downpour of 45 minutes. when I went outside now to start car, it ran rougher again. Funy. When I turn it off and restart, it goes smoothly for a minute or so before picking up roughness again.

Also:

when I got car, I changed cat on left side. Something broke off inside cat recently (maybe a piece of the exhaust pipe inside flange), and is making a marblew sound inside cat at various rpms. I also think ?I might detect something burning slightly within cat, but it's not the rotten egg odor.

Do you think my hesitation and cutting out might in some way ber elated to the cable?
