Now the weather is turning my `94 wrx wagon import is running rough when cold and seems to miss when under load. all summer it has been fine but towards the end of last winter it started doing this. This only happens on very cold mornings after being stood for several hours otherwise it is ok.

 

I too have this problem now the mornings are cooler

 

ive that problem aswell have you any idea what the problem is yet

 

same here. it idels all over the place up down up down. as soon as its warmed up though its fine.

 

Not sure if your models have HT leads if so try spraying them with WD40 or similar to disperse any moisture. Just a thought Steve
