Answer 3

yeah more than likely from what ive delt with is that the idle needs to be adjusted see not enough fuel is being burnt to keep the engine idling at a steady pace have the idle adusted or it could be fuel feed problems

Answer 4

go to autozone or checker auto or pepboys and have them hook a code reader to the car to see if there are any errors in memory. if there are none then the problem might be a bad connector to the Mass Flow Sensor (under the air cleaner). the contacts get corroded and gives the computer false readings
