Truck won't stay running
 

I have a 2000 Chevy Silverado that dies right after I start it, unless I keep my foot on the gas. Upon taking my foot off the gas, it dies again. I haven't started it since Thursday, and it is a little chilly outside, but I wouldn't think that would be much of a problem on a newer model like this.

I'm going out of town on Friday... and I'm supposed to be driving, so I'm in a bit of a hurry. Any suggestions?

check engine light on? or was on? idle too low? are u flooring the gas or just kinda holding it?

Almost sounds like a Throttle Position Sensor, or, maybe, since you mention it, an Intake Air Temp Sensor. Could also be fuel system related. Get a guage to check fuel pressure, and if it's low, you've found your problem.

if you keep your foot on the gas for a while for it to warm up will it idle then?
being a GM...my pontiac had problems with the cold start fuel injector did that.... you might check the fuel pump to,

sounds like it could be the iac - idle air control valve. Generally a $20 part, but im not sure on a newer model.

i agree with justiceforphat - sounds like an idle air control vavle problem. pretty cheap part, and easy to change yourself.

go to autozone and use their OBD 2 scanner, it will tell you where the fault is, and replace the offending part. you can scan for free @ the store, or rent it.
