I have an 89 pontiac firebird when I floor it, it starts to jerk and sound like its losing power. If I baby it it is fine and doesn't do it. It also has a rough idle and stalls when in drive with the brake on sometimes. Waht could be causing this?

Clogged fuel filter is the first thing I would check. Restricted cat conveter?
