Need Help
Hello , I have a 2005 F -350. With a EGR delete, 4"turbo back exhaust, and a SCT Tuner (running in street mode). Twice this week truck has just died. Turned key off and it started right back up. First time got code that CPS was bad, second time # 8 injector. Cleared both codes ran fine for a day, when cold feels like it is missing, but once warm no issues. Don't want to be dead on side of road what's wrong?
Thanks in advance.

What kind of diagnostic tools do you have access to? Any recent work? Maintenance stuff up to date (oil & fuel filters etc)? What conditions when it died? Accelerating, stopping etc.

You can get a false CPS code for a number of reasons, a stall event being the biggest. Check the CPS plug for oil also as the O-rings fail and cause a bad signal. With a #8 "injector code" you have 3 options so please post the specific code.

You might want to do a bubble test. The CPS code could have been from the truck dying. Search bubble test and run6.0run has a good video of how to do it. I think it's under a thread titled "aftermarket parts".

Got a scan gauge 2, My readings are this
ICP was 1600 at cold startup as truck warmed up dropped to 600
FICM main mower 48.5 never dropped below 48
Sync 0 then 1 idling
Is there anything else I need to monitor?
Thanks

Post IPCV ( volts). you can do a wiggle test at the ICP connection where the grey clip holds the 3 wires, make sure truck is running when you do this. if it stumbles or stalls you need a new pig tail
