yeah tune up? plugs make a world of difference. fuel filter?

Obvious things might be tire pressure, clean air filter. Try some fuel injection cleaner. Maybe it's time to change your o2 sensors.

If it's running cold, it probably is running rich.

Find out why it's not warming up.

Are you sure it's running cold ? does your heater work ?

Do you have a "fail open " thermostat ?

Also you might check iat sensor .

1. pull codes
2 take out the thermostat , check to see if it is
closed ( should be closed when cold)
put it in a pot of water on your stove, turn
on the heat, borrow your wifes meat
thermometer ,( make sure she doesn't see this)
and and make sure it opens around 180-190
degrees .
