I have a 2006 2.5 WRX Wagon with 85000 miles. It is not running quite right. It is rough on tickover once it has been stopped for a little bit. It starts to tick over at just below 1000rpm when you stop and then drops a little after a few seconds. It then seems to stutter every few seconds. When accelerating hard it is slow to go and then stutters a little but not all of the time?
I have had the car diagnosed but no fault codes coming up. The plugs have been changed but this didn't make a difference?
Any help appreciated!
