Big difference in cold weather;; Help me?

95 f150 5.8;;;



In cold weather (night vs. day, in Arizona @40-70*f) I can feel a big differece in the power, and take off's. Okay; I know it's because no cold air intake, but I do have an after market intake, and filter, "S and B intake" goes to drives side. But the differnce in power can't be normal. It wasn't like this once. Like there's somthing else wrong, like some sensor.

If you know, may you explain breifly what to do my self. There is some sensor that's so hard to get to, like under intake manifold.

try replacing the COOLANT SENSOR. It acts as a choke does on carbureted engines
