update on problem. took out all trac repair manual i got at work, and ran some tests. i got my vacuum pump and applied to the boost pressure sensor and with ignition on with a couple t-pins in the back of the ecu, it'll give different voltages according to what vacuum your applying. I applied maximum vacuum on the chart, and it was suppose to drop from 5V to anywhere between 3.2V and 3.5V. I only got a .4V drop, it was at 4.6V. I'm starting to believe I have a bad pressure sensor. I've ohmed all the wires between the computer and sensor, all acceptable resistance.
