P1136 code

[auh]

What are some common causes for this code? Started throwing it about 5 weeks ago. Changed the vacuum lines on the front, checked my fuel injectors, not sure what to check next.

Bumping this up. I got the p1136 today.

I swapped out my ICM and everything started working fine again. Are you missing at all?

Not sure. Not badly enough to trigger a fault code, but I don't have a vag cable yet to log the minor ones. The ICM and all coil packs were replaced by previous owner about 14 months ago. (He gave me all service records).

I'm almost positive there is a leak somewhere. 14year old car on original hoses. :eek:

When asking for a code solutions, its generally nice to put up its meaning, ergo..

17544/P1136/004406 - Fuel Trim: Bank 1 (Add): System too Lean
Possible Solutions

Check Mass Air Flow (MAF) Sensor
Check Fuel Pressure Regulator
Check Fuel Pump
Check Intake/Exhaust System for Leaks
Check Secondary Air Injection for Leaks
Check Vacuum Lines for Leaks

Special Notes

Fuel Trim Info
When this fault is stored and external vacuum leaks are not found, less obvious problems may be present:
Check Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80)
Check Brake Booster and Hoses
Check Electric Vacuum Pump ( If Applicable )
Check Crankcase Ventilation System for faulty components. When the PCV or Crankcase Ventilation System is faulty, vacuum is typically present under the oil cap and misfire faults are common.

I didn't have all that information. But I'm pretty sure you just seriously helped me solve my issue. So thank you. And I will try to be more thorough in the future.
