Looking for ideas here, about why a 98 GMC truck i'm looking to buy isn't idling until it warms up. It's got the 5.0 vortec in it.
I was thinking that it could be either the throttle position sensor or idle air control valve, but i'm not much of a mechanic. The guy that's selling it (and I don't think he knows much about modern vehicles) thinks that it just needs plugs and wires to get it running right. I will probably replace those anyways, they look like the originals and they've got mud and gunk all over the bottom halves.
The truck has good smooth power when you get on the gas, it's just that for the first couple minutes it doesn't want to idle, so i'm sure it's just some dumb little sensor or something and not actually a major problem, i'm just trying to figure out what to look for before I spend any money on it.
Normally I wouldn't think about buying a vehicle with problems, especially a construction truck that's all beat up like this one, but I can get the truck for $1,400 and it's a 98 with 112,000 miles so it seems like a hell of a deal.
If anybody has any other ideas of what could be causing it, or agrees with my thoughts, let me know, thanks.
