I diagnosed the ECU on my 3sgte today, and it blinked 3 times, and then 4 times so Im assuming this means code 34, which is overboost. How do I fix this problem?

All that means is you hit fuel cut, as several of us suggested to you on the other thread.

And all you have to do to "fix" it is shut the engine off, and re-start it. I'm sure it is already "fixed" by now. Are you still having a problem?

If you continue to hit FC, then you may have a problem with the boost control system. But if your car runs near the upper limit of the OEM boost range, it is not unusual to hit FC when ambient temps fall into the 30's. If you feel it is a prble, you can raise the FC setpoint with this:

The #35 means an open or short in the pressure sensor circuit.

Clear the codes, and see if it comes back. Since the ECU sves all errors until they are cleared, it could have been set a long time ago.
