Hi Guys, Well today I had success she fired up after a week of trying to get it going. She started on two cylinders then went to three then four blew a bit of smoke when she started but cleared after a couple of minutes and now idles fine. I gather she had been in a roll over and the plugs and pots got oiled up,I should of twigged as when I got it I had to clean out the pod filter And AFM as it was pretty oiled up.

Any way thanks to all you guys for your help it was very much appreciated, just goes to show what a great Club like Perth WRX is all about, helping each other out when were in need.

Cheers Clive
