I would go to Autozone and ask them to check your computer for trouble codes. I would expect a Throttle Position Sensor, or EGR code to be present.

Testimonial: "I also had the ideal control sensor change I forgot to include that.I had it hooked up to a computer and it said that it was all of those things that I mentioned and none of it fixed the problem. Also sometimes my anti theft light comes on when I start it."

It sounds like either and O2 sensor (primary or bank one) or it may be a MAF sensor have the car checked at an auto zone parts store for stored computer trouble codes, this chech is free and should point you in the right direction instesd of just replacing parts you may not need.

We just got a 2004 Chevy Express. When you start it and put it in gear, it dies. The battery appears dead and you can jump start it.

IAC - idle air control problem possibly .( You can drive it if you use your left foot to brake but keep the gas pedal down to keep the RPMs up.) Wouldn't be a fuel filter , if fuel filter was clogged partly it would idle ,but would lack power ,low fuel pressure at higher speed's . Do you know what IAC valve is ,an how it works ?
Idle Air Control Valve
Or maybe the EGR valve pintle is covered with carbon an sticking open .
Or possibly a dirty or bad MAF sensor - mass air flow sensor - the PCM - engine computer needs info from this sensor so it know's how much fuel to feed the engine .
Hooking up a professional type scan tool to view engine sensor data cut's down on guessing as too what the problem is .
