So I recently moved from Illinois to Florida and I'm sure this truck hasn't seen this kind of of heat consistently like this before I am getting this code all the sudden and not sure what is is and I don't seem to be having any problems yet it is P1626, I am at 270000 miles and have no idea about if its had head gaskets done and I got it at 220000. I put in new injectors and also have no idea about FPR and I get slight loping from 4.2 to 5.5 PSI especially cold, I have no idea if that's normal or not. The dash told me low coolant all the sudden but it hasn't been overheating in this weather or when I towed my camper down here, and I'm sure I had new coolant put in before I left this was a month ago, it did really good on temp so not sure what's going on but I put more coolant in the coolant tank and might put some in the radiator when it cools down and see if i need to bleed air not sure how necessary that is. I am just really hoping that I don't see that come back up on the dash I feel like that would be a clear sign of blown head gaskets but not sure, and would appreciate any insight or comments on what you guys think, I also hope my PCM and FCIM hold up in this hot weather.
