Engine wobble?
When i start the car from cold it wobbles lots. then after a few mins it goes back to normal. The car drives fine and no problems in pull.
Anyone got any ideas what this could be? it only ever does it when cold and run's fine when hot.
Friend said it might be a coil pack or a plug?
Any advice would be great
Cheers

usually break down under load or when the engine is hot.
I'm thinking more along the lines of over fueling perhaps whilst on
choke ?

me neither but if it wobbles for a short time when cold (like a carbed car would if you didnt put the choke on) then perhaps what ever enrichens the fuel supply when its cold on a scoobie isnt kicking in as quick as it should cold start sensor or some such thing sounds logical dont you think perhaps a trip to your local stealer for a diagnostic check just a thought

Picking up MY06 WRX tomorrow but when I test drove one, it did the same thing. Very 'lumpy' for the first 5-6 mile then ok. Hope I don't have the same bother !

Scoobs run very very rich when cold, it will shake and run lumpy for the first 10-15seconds of running. There is a difference from a fuel enrichment related missfire and an ignition related one, one will be much more severe and will generally present for most of the time under certain load conditions, hot or cold (but worse when cold - obviously).
If you have a car without any cats fitting and give the throttle a good poke in this first 5second of running...you'll be greeted with a plume of whitish blue smoke and stench of petrol out of th exhaust- from the unburnt fuel, and think your engine/turbo is f**ked, when it isn't
Has anyone on this board owned a carb car with a manual choke? Efi cars need same fuel enrichment - just it's automated :
