If have read the previous post then you know whats going on.

I havent been able to find the problem but i think i may know what the problem may be.
I was driving when i realized after i had installed all of the parts that i have had replaced all of the hoses from the air pump to the vacuums and so on. Before all of the hoses were cracked the primary hoses from the air pump to the vacuum was rotted from the heat all along the side. I have heard that if the cat's dont recieve fresh air they get damaged and clogged. When i drive and i have the car in OD and put it in passing gear it will start to surge and the cats on the right hand side will pop loudly a couple times and then stop and the car will just stay at about 2000-2500 rpm. And today the car also popped on my side for the first time. Could it be possible that the car wont accelerate any further b/c the cats are heavily clogged and when the fresh air reaches them the unburned fuel has accumalated to the point where it explodes?
LIke it does when i hammer the gas???

If you have any more ideas or can help me piece 2gether a solution post!!!!
THANKS
