Idle hunting

[Harun aka harry]

Hey guys i know this is a topic that always comes up but doing my head in..

Since i changed my sparkplugs car has been idle hunting ever since.

I have changed my coilpacks brand new splitfires.

Sparkplugs a bcpr7es gapped at 0.8

I have cleaned icv.

If their is a slight boost leak well that would have always been their....

My car is stock and on 10psi

I dont see why it would be afm or other things when i havent played with anything else except the sparkz and coilpacks...

Anyhelp would be appricated

Which engine? 20 / 25 / 26?

For a stock engine, plugs should be heat range 5 or 6, gapped @ 1.0 - 1.1 .

Nothing wrong with 7 heat range and gapped at 0.8mm, even on a stock engine. 

Try disconnect the O2 sensor, when they're dead generally the stock ECU goes a bit hay wire and pulls out heaps of fuel from the trim tables. If your hunting goes away, time for a new stock o2 sensor OR a Haltech (or Nistune or Adaptronic or a Vipec, etc.)
