I know it has been asked before but what are the best plugs to use in my situation?
I still have the purging, it holds back at 3k, under full load and again around 4.5k again on full load. If i ease off the gas i get no holding back, and it is not jerky at all. After reading up on here that a few owners have this issue i am going to start going through the checklist.
Had a new afm so it's not that. Next is the plugs. Was going to go for the NGK iridiums, but heard a few people running cossie plugs. I am swaying towards the iridiums, but i have no idea how to regap plugs, what this means or why it would be required.
When you buy plugs do they not come set up? or do they have to be regapped depending on what car they are fitted to, or is there a common setting they come set up for?
After they are done, if it isn't sorted its going to be a boost sensor change i think. Also i noticed that it doesn't hold back through the revs when revving stationary in neutral. only when driving.
Any help appreciated, cheers
