I was driving my little sister to school today and my check engine lite chimes on. After I drop her off I stop in the parking lot and plug in my superchips. I forget the code number now, but it told me that "Engine running cold for too long". And when i checked the temp gauge it was very low. I cleared the code and the check engine like hasnt came on again, i drove about 200 miles in all today. Any ideas why? How to fix it? Anything?? haha..i'm at a loss. Thanks!

If ya gotta fix it replace the temp sensor. I'd just drive it unless its running crappy. But also check out your battery cable connectors for corrosion and clean them real well. Some funny things happen with Rams with weak batteries or bad connections. HTH

Edit: I see you have a LOT of power eaters, also. Maybe time to have the battery load tested, new or not.

Bought a 180 Degree thermostat today, haven't had time to install it yet. The battery thing is also a good possiblity, I've been thinking of up-grading my alternator, or just a getting a new alternator. Thanks for the input!

That's not really a good idea, if the engine really is taking too long to warm and it's not some freak electrical problem it can cause damage to the cylinders. There was a big discussion on here about running even lower than 180 degree TStats and someone posted a research paper that some company did showing that if an engine isn't getting to the proper operating temp in the cylinder it doesn't burn off some of the corrosive chemicals made inside the engine resulting in premature engine wear.

if pcm doesn't see 180 in 20 minutes from start up, it'll throw that code. change your thermostat with at least a 180. stock is 195. .
