A plugged up cat will make your car barely run. Have it tested at a muffler shop. Fix any misfires as a poorly running engine will ruin a new cat.

Now to add to my issues. Cleaned out cats,good air flow now but the problems persisit. started truck, dies 1/2 block from house and wont restart ( cranks but seems no spark ) so it sits up the street from house with a now dead battery. Noticed I have a fuel build up just to right of TB housing in a boxed off area. Think this is part of the fuel meter body assembly, has 2 small pipes on top . What would cause this to happen? think it is part of problem
