Unhappy Miss Fire

Hey all,

So a little while back I got a nasty miss fire in cyl# 3. I believe that's the most common one I've seen on forums/online. So I decided to go over my history with the vehicle to see what might have been the cause. I narrowed it down to the spark plugs. I had these crappy E3 plugs that I believed caused my car to miss fire (since this issue had never occurred before). I swapped them out and got myself some NGK Premium Iridium
Part No. ILTR6A8G. I found this information here so I was certain it would solve my issue. It did, for a bit... Now I was driving today and noticed a little jerk in my 6th gear (only when accelerating with boost). I put my foot to the floor and the car jerked back and forth and my CEL came back on. Now I was pretty frustrated so I said to myself, lets try one more time... magically, no more miss fires? I was down shifting to 3rd, 4th, 5th, expecting to have the same issue...but NOTHING happened! It stopped. It only seemed to have happened in 6th. But then I put my foot the floor in 6th and nothing happened. So I'm sitting here going 190km on the highway saying, WTF?

If any of you guys have any suggestions to what is going on please point me in the right direction.

Otherwise if I can't figure this out for myself I'm off to the dealer...

Thanks!

DO NOT go WOT untill after 3k rpm in gears 1-4 and you want to wait till about 3.5k in gears 5-6. You shouldn't load up any turbo car like that.

The best thing you could have done is toss out those E3 plugs. They are beyond garbage. The next thing is to make sure you are in a safe rpm range to go WOT, and if not then downshift. This means that if you need to pass someone on the highway, downshift to to the appropriate gear and accelerate. I don't even touch 6th gear unless I'm going 70+ on the highway, or I'm shitting on some M3 on the highway.

probably cause NGK plugs suck to, you should buy denso's. Make sure they are properly gapped at .028 as well.

The denso ITV-22 comes pre-gapped at .028 (check em anyway), and are one step colder than the stock plugs. THe heat range being colder is a good thing if you have mods or even just drive fairly aggressively. The denso's can be had in the factory heat range if you're more of a peaceful daily driver stuck in rush hour traffic more than anything else.

I have tested the E3 plugs in my own speed6, and pulled them out the same day. That fancy tip does not do well in the harsh DISI environment, suffering from horrid blow-out under even slightly aggressive acceleration.

I know that having a loose filter will give you a misfire as well.
