P1281...help

My check engine light is on...it's P1281, it says that it is a Manufacturer Air and Fuel Management Problem, it might be going to the stealership on Tuesday (the 6th), just wondering if you guys can give me any insight as to what it could be, and what I can do to fix it.

P1281: Engine Cold Too Long. That's an unusual one! The Diagnostics Manual says that this code is set if the engine does not warm to 176 degrees while driving for 20 minutes after start. It says the most probable cause is a Thermostat problem. A bad temp sensor could also cause it.

well I changed to a 180* T-Stat when I changed my heater core, which was last weekend.....I'm thinking maybe putting the stock t-stat in and checking to see if that solves the problem

well I just went out to my truck and finally got around to switching my old 180* t-stat with my stock 19* t-stat, and I noticed there is no t-stat in the housing at all. Which is both good and bad, good because I just gotta get a new gasket and switch put a t-stat in there, bad because I don't remember what happened to the old t-stat, I thought I put it in there, and if I did put it in there, what the hell happened to it....I don't think these things can get sucked into the engine, or into a radiator hose, they are wider than all those things. Just a mystery of life I guess.....any thoughts?!?

I doubt that it could be anywhere internally in the engine or radiator. I would just make sure it wasn't in the engine compartment waiting to fall into the fan or something similar. Then I would put a new one in and "go down the road". Things like that "bug" me also but you will probably find it when you are not expecting to.

well problem solved, I put a stock t-stat in, and then found the one that I had put it, which I thought was 180* but it turned out the guy at autozone gave me 160* t-stat, which then triggered the temp. sensor, which caused my Check Engine Light....so, I went back to autozone and got a 180* t-stat, returned the one I bought from Dodge and got my money back, but I still have a 195* t-stat in the engine now, and next week I will put the 180* t-stat in. What a day!
