I recently took a long road trip and when i got home i change the oil,charged the ac,new wires and plugs,new map censor my problem is after charging the ac it started to have problems with having the ac on and staying running and even when the ac is off pressing on the gas it tries to stall out and it tends to cut off completely when just idling what should i do to fix this problem
Check the MAP sensor connection/connector and either the seal where it plugs in the intake or vacuum hose connection .

Ok. sounds like you have already replaced the most likely suspects, but let me ask you a few questions to see if I can help you. When you try to start the vehicle is it firing? Do you have fuel pressure getting to the injectors? O.K. this next question will sound a little strange, but it will tell me if the computer control system is working. When you try to crank the vehicle, does the RPM guage move at all while engine is spinning? Let me know the answers and I will try to help you.

Check air filter, maybe clogged. Check leaks of vacuum on the intake manifold, maybe a broken hose.

sounds like a spark timing issue. dist/coils or plugs. the only other thing and this is weird-the coolant temp sensor
