sounds more likley you have an air leak this will cause bad starting as it is sucking air in instead of fuel when its cold and wnen it warms up idling will be eratic and misfire check all hoses gaskets relating to the inlet manifold or if its done that kind of mileage crankcase pressure could be the problem but i suspect an air leak yates210456

check you mileage if the car has over 100,000 miles and you have not had a tune up it maybe time for spark plugs, air filter,fuel filter and spark plug wires if needed

Check throttle position sensor. TPS. Over time they"ve been known to develop a dead spot which usually will appear where you would normally have accelerator when driving normally, I would suppose due to repitition wearing it out at that area. If you have a multimeter (analog- needle) style, you can test it and watch needle for stumble, or drop off when moving throttle smoothly up and down.

Tips for a great answer:
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.
