Specialist Powerstroke service — shop and mobile.

Factory Ford Diagnostics

Factory-level Ford diagnostic software reads fault codes, live data, injector balance rates, and ICP pressure accurately across every Powerstroke generation.

6.0 & 6.4 Powerstroke

The two most misrepaired Powerstroke generations. We fix the system — EGR cooler, oil cooler, head studs — not just the symptom that brought you in.

6.7 Powerstroke

CP4 fuel pump, turbocharger, EGR, DEF system, and injector failures. Factory software required for accurate diagnosis on the first visit.

Mobile Powerstroke Repair

Stranded in the Treasure Valley? We roll with diagnostic equipment and parts to fix common Powerstroke failures on-site.

Common Powerstroke Problems We Fix

Every Powerstroke generation has known failure patterns. Here's what we see most often — and how we fix it right the first time.

6.0L Powerstroke (2003–2007)

  • EGR cooler failure — the most common 6.0 failure. Coolant bypasses the cooler and enters the intake. Fix requires EGR cooler replacement plus oil cooler service — skipping the oil cooler guarantees a repeat repair.
  • Oil cooler failure — restricted oil cooler raises engine temps and kills the EGR cooler. These two jobs must always be done together.
  • Head gasket failure — caused by the above failures. Requires ARP head stud upgrade to prevent recurrence. We bulletproof 6.0s correctly.
  • FICM failure — Fuel Injection Control Module controls injector firing. Hard starts, misfires, rough idle. We test and replace FICMs.

6.4L Powerstroke (2008–2010)

  • Dual EGR cooler failure — the 6.4 has two EGR coolers and both fail. A thorough repair addresses both at once.
  • Fuel dilution — fuel washing past injector o-rings into the oil. Monitor oil level and shorten change intervals.
  • Radiator failure — the 6.4's cooling demands crack stock radiators. We inspect and replace as part of any cooling system service.
  • DPF issues — aggressive regen cycles cause DPF problems. We diagnose, clean, and replace DPFs as needed.

6.7L Powerstroke (2011–present)

  • CP4 fuel pump failure — Ford switched to the CP4 in 2011. Same catastrophic failure as the 6.7 Cummins — metal debris throughout the entire fuel system. Complete decontamination required. No shortcuts.
  • Turbocharger failure — the single sequential turbo fails with age and heat cycles. We rebuild and replace.
  • EGR system issues — EGR cooler and valve failures continue on the 6.7 platform.
  • DEF system faults — NOx sensors, DEF injectors, and SCR catalyst issues diagnosed with factory software.

7.3L Powerstroke (1994–2003)

  • IPR valve wear — idle instability, hard starting, power loss. One of the most common high-mileage 7.3 failures.
  • ICP sensor failure — injection control pressure sensor fails and causes no-start or rough running.
  • UVCH wiring harness — the under valve cover harness deteriorates and causes injector misfires on high-mileage 7.3s.
  • Injector o-ring failure — oil leaks into the return system. We replace o-rings and inspect injector bodies.

Common questions

Powerstroke Repair FAQ

How much does Powerstroke repair cost in Boise?
It depends on the generation and the failure. A 6.0's EGR and oil cooler job is a different cost than a 6.7's CP4 fuel pump job. We run factory Ford diagnostic software first so the quote is based on real data, not a guess. Call (208) 809-0305 with your truck details.
What is the most common problem with the 6.0 Powerstroke?
EGR cooler failure. Coolant bypasses the cooler and enters the intake. The oil cooler almost always needs attention at the same time, since a restricted oil cooler raises engine temperature and is part of what kills the EGR cooler in the first place. Skipping the oil cooler on an EGR repair usually means doing the job twice.
Should I "bulletproof" my 6.0 Powerstroke?
If the head gaskets are being addressed, ARP head studs are worth doing at the same time to prevent the failure from coming back. We do the EGR cooler, oil cooler, and head studs as a coordinated repair rather than chasing one symptom at a time.
What causes CP4 failure on the 6.7 Powerstroke?
The CP4 fuel pump can fail catastrophically and send metal debris through the entire fuel system, the same failure pattern as the 6.7 Cummins and the Duramax LML. The fix is complete decontamination, new injectors, new lines, and a new pump. We don't do partial fixes on this one.
Do you work on the 7.3 Powerstroke?
Yes. Common 7.3 issues include IPR valve wear, ICP sensor failure, UVCH wiring harness deterioration, and injector o-ring failure. It's an older platform but a common one on high-mileage trucks we still see regularly.
Do you offer mobile Powerstroke repair?
Yes, across the Treasure Valley. We bring diagnostic equipment and parts for common Powerstroke failures so a lot of jobs get fixed on-site.
