car wont stay running

[castrodsm7]

ok so i just got my 91 talon and the guy said that the TPS was bad thats why the car idled so high and messed up...so i got another one and it runs a lil better but not like it should check engine light comes on and then will go off...when its cold the car will fire right up but after about 5 sec the car want to die..i fixed some boost leaks that i found and that made it run a lil better as well but still car will surge up and down when its warms up....i have check out a lot of stuff but and can not find the issue???im sure its right there in my eyes but still can not find it ....

if any of you guys have had this issue and you fixed it let me know what you did so i can do the same.....thanks for your time....

sounds like the water temperature sensor is bad or could be a boost leak>?

bad MAS? some times it will cause a "i want to die" idle.
