[Engine miss fire and cut out on start up]

2009 Subaru Forester

Mileage approximately 3980.

Date 07-09-09

Engine miss fire and cut out on start up outside air temp average is 60 degrees/

About a month ago after returning from 200 mile trip. The next morning upon starting the engine, it started up quickly and the RPM went up to about 1800 it then cut out( engine appeared to stop firing) and the RPM dropped down to about 500-600. The engine then fired off again and it sounded like it was running on 2 cylinders. Within about 10 seconds it gradually straightened it’s self out and ran normal as a cold engine would be expected to run. Since the first occurrence engine has been doing this each time it is started when it is cold after not being run about 12 hours.. It seems to be temperature related as the condition appears to be more pronounced at colder engine temperature. The condition is sometimes a great deal worse then at other times. A friend of mine was in the car the other morning when I started it and the engine was having particularly bad day, his remark was my that is certainly a rough starting engine for a new car.. The engine has never stalled during malfunction. The engine runs very smooth when it is warm and always starts in a normal manner when warm. My gas mileage appears to be normal about 24-25 MPG. I use Mobil 87 octane fuel.

 

 

Taken to the dealer who claims he cannot duplicate this problem. Suggested we wait for cooler weather!!!

 

 

 

have you looked at the O2 Sensors?are they wideband? if so, my 2001 OBW with the EJ25 had the same issue,would run, but after time it was barley driveable,i would suggest checking what kind of voltage ur O2 Sensors are putting out,it should be near 4 volts.

[metal clank noise when hit bump]

hello,

I have an 01 outback with 214k on it.

I have been noticing a metal sounding clank when i hit bigger bumps.

Sounds like it is coming from under the the middle of the car.

i have looked under the car but haven't noticed any missing bolts or anything that looks unsecure.

I know this is kinda vague but any ideas?

could it be anything to do with the transmission:slobber:?

 

thanks

jake

 

 

 

 

 

could be the heat shields directly under the drivers area, i had the same problem, and wen i removed mine,the noise went away, could be worth a shot.
