Hey guys, been driving my gu 2001 zd30 today and all was good. Until I went to start up up tonight to head out, when I started it up it idled like crap until I gave it a tiny rev and it went back to running ok again. Now every time I start the car hot or cold it idles rough until I raise the revs even buy 100-200 rpm and it's good as gold again... Any ideas? It's got my f**ked.. Possibly somthing in the fuel?? Not sure..
