OBD-II Code
P1611
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$80–$600
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$80 (single plug + diagnostic time) to $600 (OEM DI cassette + plugs on a 9-5, or full COP coil set + plugs on a 9-3).
P1611 on a Saab is Misfire Code Saved Past Drive Cycle — a Saab-specific status code that latches when a previous misfire event (P0300-P0304 on a 4-cyl Saab) was severe enough to be retained in non-volatile memory past the warm-up + cooldown drive cycle that would normally clear a soft code.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P1611 on a Saab is Misfire Code Saved Past Drive Cycle — a Saab-specific status code that latches when a previous misfire event (P0300-P0304 on a 4-cyl Saab) was severe enough to be retained in non-volatile memory past the warm-up + cooldown drive cycle that would normally clear a soft code. P1611 is not a diagnostic target on its own — it is a flag that says 'an underlying misfire happened and the ECM wants you to know it was real, not transient.' Cheapest-first ladder:
- Read all stored codes and pending codes — the supporting P03XX misfire code (cylinder-specific or random) is the real diagnostic target. If only P1611 is present with no current misfire code, the underlying fault has self-corrected or the customer drove enough drive cycles to clear the soft code while P1611 stuck.
- Read Mode $06 misfire counters per cylinder — Saab Trionic ECMs store per-cylinder misfire history that survives even when the active code clears, and the cylinder with the highest count is the next coil/plug to check.
- Inspect the DI cassette (9-5 B205/B235) or individual COP coils (9-3 B207) for the usual carbon-tracking, oil contamination, or worn spring contacts.
- Check spark plug gap and condition — Saab NGK BCPR7ES at 0.028-0.030 in is the spec; eroded gaps past 0.040 in cause intermittent misfires that set P1611 even after the active code clears. Do NOT clear P1611 and hand the car back without root-causing the original misfire — on the 9-5 B235 in particular, P1611 is the canary that the DI cassette is failing intermittently, and a 'just clear it' return visit is virtually guaranteed within 1000-2000 mi.

- 1997-2010Saab 9-5 with the B205/B235 2.3L turbo is the most common P1611 platform — the DI cassette's intermittent failure mode (works fine at warm idle, drops a cylinder under boost or at cold start) is exactly the pattern that triggers P1611 after the active misfire code clears.
- 2003-2011Saab 9-3 with the B207 2.0L turbo throws P1611 from individual COP coil intermittent failures, typically on cylinder 1 (closest to the firewall and the heat soak) or cylinder 4 (closest to the exhaust manifold collector).
- 1999-2003Saab 9-3 (first generation, GM2900 platform) with the B205 throws P1611 from the same DI cassette pattern as the 9-5.
- 2005-2009Saab 9-7X (5.3L Vortec V8) inherits GM code definitions and does not throw Saab-specific P1611.
