my check engine light came on about a week ago it is showing the code po102 i have checked the mass air flow sensor and the map sensor the gasket for the throttle body is somewhat gone so i sealed all i could reach without taking it out i can drive the car 15 minutes or so and it drives just fine then after it warms up it starts dying driving down the road at whatever speed if i dont give it extra gas it might die when i slow down or stop without giving it gas while holding the brake it will die while in park sometimes it dies some time it dont it will always putter around before it dies so if i give it gas it wont die some times it acts like it didnt get the gas you just gave it then it will be ok.please any help would be nice cant afford to take it to shop

2.intake manifold gasket leak (also common with this vehicle)
3.Vacuum leak at throttle body (Has to be removed to replace damaged gasket )
4.Vacuum leak at EGR valve flange and pipes.
5.crankcase ventilation valve faulty or incorrectly installed.
