Truck is 08 job 3 F-250 270,000 miles billet S366 NL CAI all normal deletes GH tuned.
about a week ago truck started to lope at idle when first started in the morning (70 F) then return back to steady idle within 2 seconds so didn't really pay much attention to the loping idle at first morning start up.
Fast forward a week later now.
Truck was running fine yesterday then today pulling from a stop light at light throttle TC locked lost power (dead pedal) and regained power (I wasn't paying attention to RP) within a half a second (Full tank of fuel) now the truck will idle higher than normal (800-825) normal (725-750).
Checked for codes with the DD and AE no codes oil level is full no fuel smell coolant is full,no weird noises,no excessive blow by checked upper fuel bowl fuel is clean and no water.
Drove it home thought the tune went corrupt return back to stock idled normal turned it off and reloaded the GH tune let it cool down started it back up idling at normal idle rpm (700-725). I test drove it down the road and stopped on the side to check the idle (still idling norma)l then I did a WOT run and back to high idle (800-825).
Checked injector short term fuel trims they are normal.
Starts up normal
RP at idle is 5000-5100 (Gearhead Race SCT)
A few days ago I logged a WOT run 24664 at 1.808 PW seem a bit low?
Power balance is perfect.
No abnormal PIDS.
EGTS are 1300 WOT
No P0088 or P0087
I do hear a slight whining noise coming from the LPFP on the rail.
I'm going to get a fuel pressure gauge tomorrow and check FP at idle and WOT.
I read that at the fuel cooler the pressure should be 3-8 PSI?
Thanks in advance
