ok I looked at the other threads and found out that Idle "puts" are normal. That was my first question,but I have another. After the car is warmed up I rev it and when the RPS's drop after letting of the gas the engine wil make those "puts". This is what it is like R for rev P for ''puts'' rrrrrrrrrrrrrrr then I let off ppppppp then normal Idle. Then car kind of shakes when the ppppppp's are taking place.

It dosent "put'' when reving up only when I let off and the rps's drop.

I put new spark plugs and wires in I thought this might be causing it but no.

It feels like the exhaust is clogged of something could this be the problem? My exhaust is real old and rusted my new one will be in on monday.

maybe you have a hole in your exhaust which is causing that.

I have holes in the cat-backs is that whats causing this?
I have a new exhaust on the way so I will see if this fixes this.

I think you might be describing backfires? I dunno. Your description is kinda vague/poor.
