TransAm engine troubles

I have a 93 TransAm. As soon as it warms up it
starts to sputter and rev up and eventually die.
I have replaced both oxygen sensors and the
catalytic converter, also the fuel filter and spark
plugs. I live in germany so there is no competent
mechanics around. The trouble code is 26 and the
diagnostic that was done said it was the #1 & #2
quad drive. Does anybody know what else this could
be? The car will only run for about 10 minutes
before it acts up. I am out of ideas.

    Common causes of the quad driver crcuit codes are a bad air bypass solenoid,bad egr solonoid or a bad ECM.The quad driver is part of the ECM and if it is bad,the ECM will have to be replaced And if the ECM has to be replaced,make sure you replace the PROM along with it.Click on my name and it will bring up my profile,there is a URL there that if you explain the problem,they will possibly post a diagnostic chart for the code 26,so you can determine what exactly needs replacing.
