1)car is hard to start, 2)when started can die in a intersection,

yes .it also sounds like your alternator has failed.get it checked

needs new red top battery and a new nz1 starter motor

Take it back to where you got it and make them refund your purchase price. If they refuse and you finianced it go to them, There a law called "The Lemon Law" that makes it unlawful to sell something like that. Sounds like you sure bought one. Don't do anything to it just get hold of the place where you bought it and tell them to come get their junk out of your yard! dhgill1949

If the motor gets hot and cuts off and will not start for a period of time the problem would be the crank sensor. The sudden cut off and starting right back up can be due to dirty battery cable connections. Remove them from battery and clean all three of them with a wire brush and replace both bolts.

check to see if it is losing vacuum at the brake booster

clean the throttle body most common cause of idle/decel die off. its cheap and real cheap and easy to do yourself

although you don't want to the best thing to do is take it to the dealer

If you find that the engine is dying at intersections and runs a rough and fluctuating idle at start up, and you also sometimes lose power even though the engine is running then it is probably your Air Flow Meter or sometimes reffered to as a Mass Airflow Sensor. Eventually, as the AFM deteriates further you will no longer be able to start the engine as the ECU can no longer get accurate flow readings to work out air fuel ratios and shuts it all down to stop damage occuring. 2 ways to fix, replace AFM or upgrade your ECU to one that is capable of running MAPs for air fuel ratio, rather than using a sensor. Hope this helps.

Most likely right.... if the alternator quits you can often run off the battery but once you start accessories like wipers . heater etc it will not last long
