I'm having troubles with my Subaru Outback stalling intermittently.
They Symptoms of my car is:
- It stalls on idle
- It stalls while driving with no warning
- While driving I can feel the engine loose power (revs drop) theres no response from accelerator and it cuts out OR pressing the accelerator makes the engine pulsate from no power to some response from the throttle a couple of times before either stalling or it goes back to normal.
- Theres a humming/whistling noise coming from the air intake area, it doesn't start making the noise untill about a minute after I've started the car
- No Check Engine Light has come on
- No codes come up when scanned
- As soon as it cuts out, it starts straight back up. Sometimes after the car cuts out it starts then cuts out staright away etc a couple of times before it starts and doesn't cut out. While this is happening I rev the car and it's as if the engine is trying to clear something?? Maybe.
These symptoms don't always happen. I can drive 100km and its absolutely fine and other times it just cuts out again and again. (The humming/whistling noise always seems to be there though)
Work done on car to try and fix the problem:
- Air Flow Meter has been replaced
- Fuel Pump has been replaced
- Fuel Filter has been replaced
- Throttle body has been cleaned
- IACV has been cleaned
- PCV has been cleaned
- 2 small vacuum hoses around the IACV have been replaced
- Pressure test done on car to rule out it being a blocked catalyic converter
Any ideas on what it could be?
Thanks
