I checked my codes and at first I got.

1. ignition signal circuit 0201
2. fuel tank temp sensor 0402
3. rear 02 0707
4. vac. cut balve bypass valve 0801
5. evap canister purge valve 0807
6. evap canister vent valve 0903
7. fuel pump control module 1305

I cleared the codes and let the car idle a while, and I rechecked. I got these.

1. fuel tank temp sensor
2. vac. cut balve bypass valve
3. evap canister vent valve

The only one I think may rob a little power it vac. valve. Any thoughts?

What happened to throw all those at once?
The fuel related ones are rather strange...

Well the car has been liberated of nearly everything not needed to run down the track.

also what purpose does the evap system serve?

Evap recirculates fuel vapor from the tank and sucks it into the engine.. not sure if the ECU adjusts a/f slightly to allow for this or not..

you've removed your electronic EVAP assmebly to cause all that. I personally think it doesn't do any power robbing at all. I have a 95, running a canister EVAP. bought a 96 JWT ECU, which runs a electronic EVAP. I have the same codes you have, and the car still runs "JWT" strong...

I think EVAP problems just give worse gas mileage.
