I changed mao sensors, and the code is still there. I checked wiring, and thats ok. Oh yeah, I have a 99 gsr motor in my 92 vx. There is a vacume line just off the back of the intake. where does that go to? i think thats my problem, I have 2 hoses that can go on there. 1 hose from the black canister, and 1 hose from the black box below the hood in the middel. Help me out please.

 

I believe that your 92 had an externally mounted MAP sensor, the on the firewall. The 99 GSR should have its mapsensor mounted on the throttle body. All you should have to do is plug up the vaccum line (so it isn't connected to anything) to the sensor mounted on the firewall. Reset the ECU too.
