Please help
 

I dont know what the problem is anymore. got the random misfiring fault after i put crap bosch plugs in it and i swapped them back out with ngks but im still getting the fault and now with the NEW fault for fuel pressure drop to the regulator or something. idk ill look at it again and repost the codes. And then also that little tempature thermometer was blinking and beeping and a fault came in for checking the coolant system. Its like 10 degrees here outside...ummm and on top of that ill tell you that the coolant in my car is some crappy prestone replacement and not the G12 lifetime that should be in there. can ANYONE help me find out whats going on with all this???

The little red blinking thermometer means that your coolant is low. If the coolant isn't red, or the kind you need, it will gel up your system then you need to flush the whole thing. The other codes could be from the plugs but I doubt it. Fule pressure reg might be going bad, reset the codes and see which ones come back.
