Hi there, I have a MY95 WRX Sti and it's all over the place when it's cold. I have already changed the coolant temp sensor, as after reading a few threads on here regarding the same thing thought this would be the most obvious bit to do first.
It's still doing it though, only first thing, once it's warmed up a bit it's ok, and it doesn't like the rain either.
Would just like other people's opinions before I go down the coil pack route (and they are the two bolt ones as well so not going to be cheap). Ta, Nick.
