got a cel,
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:
o Check Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80)
o Check Brake Booster and Hoses
o Check Electric Vacuum Pump ( If Applicable )
o Check Crankcase Ventilation System for faulty components

I have no vacuum leaks and a brand new maf sensor. Any other ideas? Car is bone stock other than a neuspeed intake

 

hey bud, any luck with that p1136 code?? throwing the same one..car sputters as soon as it starts boosting and wont accelerate too much if any at all (MAF Plugged in; tried 3 different MAFs{2expensive ones and a cheapo for the correct engine code}). i think i need to try the N80 since my car never starts unless i pushed down the accelerator after i fuel up...

get back to me!
