R33 Idling Like A V8/wrx

[Soulslider]

Hi guys I've been having issues lately with my R33 it runs good for whilst driving for about 15 minutes, then it starts to idle rough almost idling like a v8 but when I put my foot down it goes back to idling normal ? I changed the coil packs about 4 months ago I have been told it could be my afm playing up

Cut the AFM open and solder the pins, there is a 'how to' on here somewhere.

Cheers I did that still got the rough idle I'm guessing it could be a faulty coil pack. I did buy them off eBay lol

It sounds like a wrx because its not firing all cylinders, buy yourself a reputable set of coil packs.

Changed the spark plugs?

I had that same issue. It turned out to be the ignitor.
