My car sputters when I start exhilarating between 20 and 50 kms, when above 50 it runs smooth, also idles extremely well and starts just fine. I have owned this car for the last 2 years with only 145,000 orig kms. I do know that I need a new Catalytic converter, Could this be the problem?

Heres a long shot, check out the EGR valve it may be plugged with carbon. But first check and or clean the Mass Air Flow sensor. You can go and get a can of MAF cleaner at any auto parts store. just follow the directions on can. The fine wires may be dirty or corroded on the MAF sensor. An engine with a bad MAF sensor may be hard to start or stall after starting. It may hesitate under load, surge, idle rough or run excessively rich or lean. The most basic test is to unplug the MAF while the engine is turned off, and then start it. Most of the time it will run better without it, if the sensor has failed. Good-Day!
Possibly a leaky injector bleeding down the fuel pressure. First check fuel pressure at shutoff, start, and then when it's smooth. If it changes a lot, you would have to raise the fuel rail and power on the pump to see what is happening.
Does it use spark plug wires or individual ignition coils for the each plug?. My 98 intrepid uses coils and occasionally I have to change them out cause it would start to miss when normal temperature was achieved. If it uses wires, try replacing them, along with the spark plugs.
indicates problem injectors
a cheap test is to run a couple of cans quality injector cleaner through the fuel tank and if that doesn't improve it have the injectors cleaned and checked
while that is happening run the fault codes to check for other problems
Take the EGR Valve off and clean it with a non-chlronated brake cleaner and a wire brush.Sounds like the EGR Valve is stuck in the open position this will make the motor idle rough but running over 45 mph its smooth.
It could be a fuel filter, Mass Air Flow sensor, extremely dirty air filter...in other words a number of things. Check the air filter. If clean or ok then, while at idle, disconnect the MAF sensor plug and listen for a differance in idle speed or smoothness. This ONLY tells you the MAF is "doing something". lol. If idle remains the same, you'll know the sensor is a problem. (check a manual or the owners manual for exact location of the MAF sensor. It IS in the intake hose/filter box)
It also could be clogged/dirty fuel injectors. Try putting a name brand cleaner in the tank. Berryman B12, STP, Lucas, ect ect. and drive it (if possible) at least 50 miles. Let it sit and run if not drivable, keeping an eye on the temp. Some overheat on extended idle.
Good luck. :-)
Somewhere along the the line you may have a fuel blockage or a good dose of water in your fuel tank.Check the water in tank 1st.Add 1 litre of metholated spirits to every 20 litres of fuel.This will allow the water to break down and be burnt through the motor over time.Do this twice.If this does not work,there may be a glob of **** in the fuel tank that blocks the pickup.If this is the problem,the tank needs to be taken out and cleaned.I hope this is a start to get you back on the road.
Try having your fuel injector cleaned, you can start with running fuel injector cleaner though your gas tank and if that does not help then you have to get it cleaned out professionally or even worst have the injector's replaced if they are bad.
The other thing that will give it bad fuel would be a bad air intake temperature sensor go bad, as for the ruff idle that is common to a dirty or stuck EGR valve.
Good luck and keep me posted, by the way, what kind of Garage did you take it too? And are there and DTC codes from the ECM?
ok try this,first your loosing fuel,so find a local parts store and see is they can check the ign module.it controls the fuel pump.as does the crank sensor.also check the ign rotor to see if its burnt through the bottom.
