Car idles fine, dies when accelerated

When you press on the gas when the truck is running, does it rev up?

Did it die while driving down the road (foot on the accelerator) or when idle? - If so, try cranking it and get your RPMs up to 1500-2000 RPMs and put it in drive (with your other foot on the brake). See if it will continue running if you never take your foot off the gas.

There should be a purple wire with white tracer from ignition module to computer. That wire carries rpm signal to computer, w/o that signal, the computer won't ground the fuel injectors. With the engine cranking, you look for a dc pulse on that wire. If you have a digital multimeter that has a tach--duty cycle or dwell setting, it should react to a dc pulse.
My info on your model year, isn't that great.

You don't say what engine is in it (2.7 or a 3.2) but you need to check to see if it is getting spark at the plugs-it may be the crank sensor, weak links in Chryslers of this era. pull a plug just to be certain it is getting gas, but I'd guess it is a crank sensor.

no its not the crank sensor if it were your car would not even start. your problem most likely is the idle air control valve, try removing it and and cleaning it if it does not help it will have to be replaced.

idle air controll motor is bad

SERVICE IT .....OIL PLUGS, AIR ,FUEL AND OIL FILTERS GET TROTTLE SENCOR AND THE MASS AIR FLOW SENCOR CHECKED

RUN down to Advance Auto Parts and buy a can of "SeaFoam" and add to your gas tank per instructions (more is not better). Drive for at least 100 miles and the problem should subsist...providing you haven't been driving it alot with this condition!
Your O2 sensors in the exhaust are fouled...Do NOT go to the dealer for a fix...you'll spend $600 there...and good mechanic should be able to do it for $200 less than a dealer.
Good Luck

For all those out there that have had problems with your Chevy Aveo Stalling, inconsistent idling, hard to start, or throttle problems, Hollywood Harv has the answer for you. Try a new Valve Idling Air Cont GM part number 93744675. You only need one and it has to be install by Chevrolet so they can place in the codes to make it work properly. Toss the old one away as most likely has so much carbon build up on the part that it stuck or struggling to function properly. It worked on mine after many different attempts at other stuff! This is a sure winner! Good luck and drive safe! Hollywood Harv

check your airfilter. your dirt road is killing it much faster than driving it on pavement

I had a similar problem, do a compression check you may have a valve problem.
