I'm not sure if they're stuffed, or whether the fact that 3 of the coils aren't being held down by the rubbers (lost them somehow!)My question, is would either of these things affect 0-100 performance? I've always felt my car was a bit sluggish for some reason...Just did a 0-100 test with my 11psi tune, and one stock tune... and the 11psi was slower!Got 6.4 seconds on stock, and 6.6 on tune... what the? Could this be because of the coils? CheersDave Link to comment Share on other sites More sharing options...

I would suggest getting some rubber or thick foam to replace the originals and see how you go. If you get a chance, pull the coils out and see if there are any white marks on the ends - this will show arcing - as this will mean the spark isn't going directly into the plug.

Have you gapped your plugs to 0.8? that's always a good idea with higher boost Link to comment Share on other sites More sharing options...

QLD Posted 07/09/08 08:32 AM Author Share Posted 07/09/08 08:32 AM Sorry I should have used my last thread.My question this time was whether it would have such an affect on performance. I'm going to replaced the rubbers, but Im just hoping that the performance picks up once that's done... I have updated my plugs. I'm using Falcon LPG plugs, apparently they're good for tuned turbos.

But this problem happens with or without my tune loaded...When I lift the rocker cover garnish, no coils are sitting high... I'm thinking they might just be stuffed though, because although it idles fine, under load it splatters.Apparently the coils can arch only under load because of the pressure increase? Does that sound right?I've changed plugs twice now, and the problem is still there, so its nothing to do with them... And I've tightened the hell out of every bolt on my manifold/turbo so there shouldn't be any exhaust leak.I'll get some rubbers, see how that goes. And if its still being a pain, I'll replace the coils (probably due for replacement anyway after 150,000 highway k's)... Link to comment Share on other sites More sharing options...
