I have a 2005 F350 with 251K miles on it. I starting having this problem about a month ago while I was driving my gauge would fall then come right back up. I thought it might be something with my HPOP
so I tore my motor apart and resealed my HPOP
along with the STC upgrade. I checked my LPOP
and it would fill my oil reservoir just fine heck it even started with the cap off and filter out. I do have a 58v FICM
, studs, Edge tuner, Power max stage one turbo, spear co intercooler, and a coolant filter. That is all my mods FYI. I replaced the oil pressure sensor and still no fix. I recorded some information on starting and running.
Start times are between 1.81s to 2.5s
at 70mph my motor was at 20% load. My ICP
was at 1345 psi
at idle at a red light my motor was at 36% load and ICP
at 635 psi
at idle in park my motor was at 21% load and ICP
was at 570 psi
Honestly I am just trying to fix my dash gauge problem. It will rise when I take off and fall at idle. I don't have a hard start or anything just want my damn truck to stop dinging at me. For a short time fix i just have it unplugged. Does anyone know what might be my problem?
