(Not a Car Question?)

I have a 1994 Buick Lesabre with the 3800 series motor in it. It will start up and idle but when you try to accellerate, it bogs down. I can pump the accellerator pretty fast and build the rpms up, but it wont stay. ive replaced the EGR, the air intake sensor, the throttle positioning sensor. Sounds like it might be stopped up at the catalytic converter.

Optional Information:

Already Tried:
