2002 stratus, hesitates up to like 30 mph, drives fine after that but does struggle on inclines. Recent work new water pump, timing belt. Any ideas. Someone said might be bad cat? Has new plugs, wires, tps.

Do you have a check engine light and when was last tune-up?

http://www.2carpros.com/articles/engine-hesitates

Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing.

USUALLY A CAT SEEMS TO ACT WORSE THE FASTER YOU GO. AS THE ENGINE MUST EXPEL MORE CU. FT. OF EXHAUST, THRU A RESTICTED AREA.I MAY BE WRONG!

USUALLY A NASTY FUEL FILTER WILL EXHIBIT THE SAME REACTION, AS FUEL DEMAND INCREASES. BUT ACTUALLY DELIVERY IS UNABLE TO INCREASE

I BELIEVE YOUR PROBLEM IS DIFFERENT

IS YOUR CHECK ENGINE LIGHT ON?

WHEN DID THIS BEGIN (TIME PERIOD OR IMMEDIATELY AFTER WHAT WORK WAS PERFORMED)

CAN YOU BETTER DESCRIBE SYMPTOMS. ENGINE? TRANNY? MISSING? JERKING? ETC?

IF YOUR CHECK ENGINE LIGHT IS ON. MANY POPULAR AUTO PARTS STORES WILL EXTRACT THE CODES WITH A SCANNER FOR FREE!

IF THEY WILL TEST YOUR FUEL PRESSURE GET THOSE NUMBERS TOO!

SOMETIMES THEY WILL EVEN DIAGNOSE/ SELL YOU PARTS/ SHOW YOU WHERE TO INSTALL 'EM

EVEN SO, TELL US WHAT THE CODES ARE. SOMETIMES THINGS JUST DON'T GO SMOOTH!

YOUR TURN
