...I would start with the canister purge valve (aka solenoid purge valve)...I had a similar problem and it was a bear to find...It surned out when I took a turn or bump, mine would hit the wires against metal and ground out...You would not believe how much the computer relies on this one item...

...From your tps, egr, and spv codes, this makes me think that you have disconected/damaged/ or shorted wires...

You can test your solenoid by cutting a wire harness off at the junkyard and putting 12volts to it and trying to blow through it. Should be closed with no power and open with power. I'd probably grab a solenoid at the junk yard while your there. The hoses and the tee on the solenoid break easily so leave the hoses on the solenoid and pull them off the canister and the nipple on the intake.
