P0420 catalytic efficiency
i have a 99tl and got a code p0420 which I had before and replaced the catalytic converter (direct fit but it wasn't no $600, it was more like $100), but after about 5-7k miles the code came back on; however, this time the car hesitates, like it wants to stall when I accelerate. Any suggestions?
