Thanks for the comment. I understand the temperature business. The vehicle does it every morning all the vehicle has to sit for over 12 hours or like over night. It has done this same thing for over 30 morning starts. I took it to the dealer left it over night for them to check it out. The service rep parked the car and said he it would not be moved until the next day and I suspect that did not happen. I called the next afternoon and was told they want to leave it sit for awhile longer because they had changed the plan and serviced the vehicle prior to diagnosing the problem. That was not suppose to happen. It is a mess. This AM the OAT was 60 degrees vehicle had sat for 15 hours, engine started immediately then cut out and RPM dropped to 400 the it fired on a couple cylinders, then finally straightened it self out.

Thanks for the reply. I did not notice any smoke. This whole occurrence lasts only about 15 seconds. It seems like my immediate action to take is to put pressure on the dealer. I will post what the corrective action when ever that happens. mr.ed

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!!!
