i really hope someone can help with this. I have a 2012 f-250 6.2 gas.it will start up and run fine. when the engine temp hits 165 thi idle starts to go up and down then stall. It will restart and do the same thing . then it will re stard and run like nothing is wrong. it wont happen the rest of the day. I let it sit for 5 hours and it was fine. it seems to only happen after it sits over night. I changed the cpv and pcv. thanks for the help
