Help! New serpentine belt, now idles way low almost dies.

Let me start off by saying I know very little about working on anything mechanically and usually have someone with much greater skill watching over me when I do anything... except of course this time.

I just threw a new serprentine belt on my 2.7L. I was feeling very proud of myself because I managed to get the old one off and the new one on fairly easily. I fired up the truck and it ran fine. I drove it up the street and back and all was well. I even parked my truck on the street (with it running) to move a car back into the garage where I was working on my truck. It sad and idled just fine parked on the hill.

Then I hope back in a drive up the hill and it about stalls on me. I thought it's because I was on a hill and just dropped the clutch to fast. But at the next stop sign I notice the idle is dipping way too low. I have to blip the throttle to keep it running.

The little bit of mechanical know-how I've picked up along the way tells me I've thrown the timing off. Can anyone please help?

 

I can almost hear the grumbles of, "Stupid n00b."

I think it's actually fine. I just fired it up and let it sit for a little bit. The idle dipped a bit after I blipped the throttle but it didn't die. The rpm's crept back up a bit.

I took the battery out to clean out some gunk around it and I think the computer was just resettling itself (feel free to tell me if that's utter nonsense).

There's just something about working on your own daily driver, then having it act up that just makes you feel like your gonna barf.

 

By r&r'ing a serp. belt you wont throw timing off. If you took the battery out in conjunction with doing the belt, your truck is just resetting itself.

 

Yep, it sorted itself out. When stuff like that happens I just always assume it was me doing something wrong lol.

 

Yup.

Wife left her dome light on.
Battery was already 4 years old so I binned it.
Ran like shit for 2 days... gradually improved and was back to normal by the next afternoon.
