won't take gas?

OK I got it started and now I have the same problem that I had before I put the new head on? The car will start and run but when you give it gas it just chokes out and dies? I replaced the MAP, all new wires and coils. this 92 2.2 is really becoming a pain! I changed a couple of vaccum hoses and that is about it. Any idea's on how to keep this running would be good.
Thanks
Bob
