Scan for codes and check fuel pressure first. Then check vacuum at idle if 15" or belwo suspect clogged converter.

Thanks for the speedy reply, is it the catalytic converter you are speaking about, this was removed a while ago trying to fix this problem. Do you suspect the air flow sensor as being defective? Is the car supposed to function when it is disconnected.
