Anyone got any other thoughts? Gona buy co contact cleaner today n clean afm. Can someone address the above questions if they are awake yet thanks

old plugs showed no signs of fouling, as far as I could tell with regards to coloration and wear. Plus now the plugs are new (however possibly have the iridium + boost = dillema) is there a way to isolate the o2 sensor as a possible culprit? Or in my case, actualy locate it! Thanks for u help so late (if I dont reply any more it means my brain went into a sleep deprived coma, to Wich I'll respond asap in the morn)

at times I feel that it is worse when cold. Esspecialy those first realy yucky severe kinda ones at lower rpm. That's always heaps worse when cold. And eases off (doesn't stop though) after driving for a fair time. but as for the higher rpm one. That severity remains the same no matter how long I've been driving for. But as mentioned in first post, it may (rarely) not even occur, it won't do it maybe every 3rd attempt. And when it DOESNT occur, I don't know if this is in my head, but the power feels a bit lacking.

umm. One would assume so. Honestly. I can't know for sure. They were put in when I needed a new coilpack a while back. The boys down at HPF/Amberly Auto did it. They usualy are pretty on the ball down there. However who knows. What u recommend the gap be at? These iridiums are .8 and cos the coppers where the same heat range I assumed they where .8 too.

however correct me if I'm wrong, you've obviously got alot more know how than myself, I'm just confused cos it originaly had coppers when this problem started

hmm. Fair enough. Lol but it had ngk coppers in it before I change coilpacks n plugs. I only changed to iridium and splitfires BECAUSE of this problem. That's why I'm kinda thinking it's not an iridium problem, as it did it with the coppers. So what else could it be?

how would going to a cooler plug help? When I swaped to iridium, the old plugs were coloured perfectly, not indicating detonation or other nasties (had light tan colour, no damage to tip or ceramic etc) please advise...

Is this serious advice?

ahh ok. Lol. Went in a few times n spoke to him. Then he left n spoke to ummmm I duno mark I think his name was. N he gave me a card for status tuning. N I noticed it in ur sig lol

btw do you know a justin that worked at autobarn narre?

thanx ill try that... ha

so completely unbolt and drown in CO contact cleaner? any special precautions? (allow to dry? dont spray directly on wire, etc etc?) thanks

Also need to mention... when i slowly ease on the throttle, it pulls nice n smooth.. the further down i have the throttle the more it starts to hiccup etc... esspecialy at low rpm under load.... thanx again edit: i did mention it already in the first post :smackhead:

Okm started it up, and tried messing with the AFM, tapping it, fiddling with the loom, the clip, giving it quite a bit of shake, more than id hope would be going on under normal driving onditions, n not so much of a hiccup. i took off the pod n tried to have a look at the state of the wire, could only look through the mesh, and wasnt sure what a clean AFM wire should look like.. im in the process of trying to find an image on here showing the difference between a clean n dirty AFM wire... any help on what a clean wire should look like.. as i couldnt see clearly and it looked like there was a bit of a buldge in the middle of the wire, is that grime, or a little sensor??? lol Annddd any other suggestions to the cause of this problem... many thanks in advance... Tys

ok thanx I'll give both things a try. Ur suggestion and the other of checking to make sure AFM wire is clean. N I'll report back. Was ur problem mainly under load? Cos this is. Idle is fine. Cheers

having said that it may have been happening before my controller was put it, and I may not have noticed. As I seethe boost higher higher (7,8,9,10 I have four presets) the symptoms get worse.

since I had my boost contoller put in. When it's set at 10psi preset I feel it the most. When I put it on 7psi preset I feel It less, or much less severe I should say, still as frequent. Howeever as increasing boost increases fuel and changes a bunch of engine aspects, and as the boost appears to be holding consistantly I seem to think it's not a boost issue.

ok mate will do. Thanx for the suggestion. Is it likely to be that dirty as I'm running a dry pod setup? Thanx again Tys

Hey everyone. I had a search on the forums. Found a couple topics sort of on the same brain wave but no exactly what I'm after. So forgive me if this has been coveren n just past me a link to where the topic is ok... My car has serious "power delivery" issues. Down low, as boost begins to come in the car will hesitate n stutter like mad (has better and worse moments. sometimes won't happen = rare though) and the car feels realy "bogged down" and hesitant. Not the smooth kind of "I'm running a bit rich" hesitant that creates flat spots either. Once the revs start climbing the initial "rapid/harsh" kind of stutter dissapears and is usually replace with a more minor stutter (still 100% noticeable) right through to redline. The low rpm initial symptom happens practicaly always and can only be avoided if I let the revs wind up a bit (bout 3-3.5k) before putting the boot in (to which I will get one short sudden stutter before revs climb nicely) to which I'm then greeted with the next stuttering feelinG at higher rpms probably every 2 out of 3 times I attempt to let the revs climb for longer then about a second or 2 after the initial stuttering. (following so far? Lol) I've tried to monitor the boost as this happens and it appears to be climbing steadily. And the boost doesn't seem to cut when the stuttering starts. Ok my setup. Nothing fancy. It's a r33 gtst s2 manual. Pod. hks cat back (or just rear muffler not sure,looks like a catback, although pipes seem a bit small) Gizzmo digital boost controller (10psi) Splitfire coils Ngk iridium plugs pre gapped to .8. Heat rating 6. Rest is stock. Now the coils n plugs I did last week to try rectify this problem as my mechanic took a quick spin n suggested it feels like a coil or a plug. Having replaced a coil earlier on I thought screw it I'll get the whole thing replaced. Obviously to no avail which is why I'm here. Before I waste any money taking it to my mechanic/tuner has anyone got any thoughts. Unfortunately this is ruining my enjoyment of my line Thanx in advance. Tys

sub model number please might be interested.. cheers...

wine cooler still up... been used once overnight to check if working. even though its not a fridge as such, it still managed to cool a bottle of drink nicely
