Hey Guy's anyone out there ever seen a clogged Cat on a 96 vintage Sentra? I have been through just about everything and I am still having problems getting this thing to move out of it's way? The engine is fairly new the timing is on,I have No check engine light's. I think it might be fuel pump related though? It always is tough to start first thing in the Mourning after that it starts fairly easy? I am grasping at straws here guy's? Maybe the cat is plugged? Nah I think it's the fuel pump? I pulled the thing for ha ha's the other day to see if things were plugged and the sock was big time clogged. You would think it would get better? Well it got a bit better but nowhere as good as I had thought it would be? I only owned one other four cylinder car and it was a Mercury Topaz. Well that little car had twice the guts as this one? I think there is something wrong still Help guy's what can be going on here??
