Could PO430 cause this?
Supposedly my cats are below efficency threshold and I have a hesitation from idle-2500 when the car is warmed up. Also have a bad tps sensor, don't think these are the culprit b/c I had this hesitation a month or so before this ses lights came on. Any ideas? trying to rule things out. If not this, will have to hook hp tuners up and see what's happening.

Bad cats normally means they are damaged and are restricting flow also, That could be a cause for loss of performance, however, A TPS SENSOR is very important for the car. and if you say you have a bad one then get that replaced asap. It is a cheap part and is used for just about everything on your vehicles tune.
