Ive got my v4 wrx, i took it from oamaru to nelson and back(for th fours and rotors) did over 1700km all up. Ran amazingly well. got home turned it off and it sat for couple of hours. Got back in it to pick misses up from work and it idles fine then runs on like 3 cylinders/misses badly then runs good then does again and it carries on. once over 1500 revs it runs great boosts fine etc just at idle it doesnt run properly. the only thing i did differently while i was away was i had to use a tank of 95 instead of normal 98 as nelson doesnt have 98 lol
I havent had a chance to look at it yet as im too busy doing house renervations but thought you guys might have an idea of what could be going on???
Will have a look this week.
Any advice will be great.
