Good evening guys!
So, I havent posted here in quite a while, just thought I'd stop in, give an update, and ask a quick question...
To make a long story short, my last thread here was asking for opinions on the 2004-ish F250's and 5.4liter engines... I was looking at one that was a former game warden vehicle and I ended up buying it
I got it for $3k under bluebook since it "idles rough", but I was able to fix that problem - usually - with a $28 air idle valve...
Now the question... When this truck has been sitting for a while, it always starts normally, but the RPM's drop/sink way too low unless you're giving it gas. It used to always do this before I replaced this valve, now it only does it after the truck has been sitting...
For instance, I recently replaced the transmission fluid and filter... And promptly crushed the gasket like an idiot... The truck wouldnt stop dumping ATF everywhere... And I let it sit for ~3 weeks until I had time to replace the gasket, which I just wrapped up this afternoon...
When I started the truck, its idle RPM's dropped like a rock, and it actually stalled out while I was backing up, something it's never done before... Any ideas what could cause this? Unless its been sitting it runs like a dream.
Anyway, thanks in advance for the thoughts.. And enjoy the video I made when I brought this truck home!
(I've since changed ALL the fluids, and had the brakes replaced, but in the video I mention needing to do all of these things)...
