Truck sat for a month, problems!

[itzbutters]

I haven't driven my 2003 GMC Sierra in about a month straight, I went to start it up today, wouldn't turn over, gave it a jump with my portable car charger, started up. Went to drive it around and it stalled right after i left the driveway, after letting it idle for 10 mins(which brought no problems) I tried to drive again, it stalls after i give it gas and the RPMs go low. Stalls at almost every stop sign, if it didnt stall, it wanted to. I hear it could be the Idle Air Controller, i plan on cleaning that off tomorrow, but i wanted any input from yall on this forum, thanks.

Dirty IAC will cause the issue yo have mentioned above, but also a dead battery will cause the IAC to loose its settings. You may have to do a IAC reset.

To reset the IAC valve, depressing the accelerator pedal slightly. Then start and run the engine for 5 seconds, then turning the ignition OFF for 10 seconds. This should reset it and restart it without the help of the gas peddle being depressed.

Keep us posted and stay safe
