I recently put a turbo xs dp and tp on my ms3. Plus I upgraded my spark plugs to ngk one step colder over stock. Well, I gapped the plugs to .028 b/c with the cobb accessport, it said that was recommended. Also, I'm running the cobb stage 2 with cobb sr and turbo back exhaust. the V103 map. Well, I had a miss fire today and I was hearing a knocking noise under the hood so I checked it out and my number 4 cylinder spark plug, the electrode was gone! So I put the stock plugs back in and my car is still miss firing and I now have a vacuum leak, lol!!! Well, thats what my codes are reading so. I'm kind of in a bind here. What should I do, since my warranty is now voided, lol. I'm basically lost, also the knocking noise only happens at boost, around lie 4-5k rpms and at idle it feels like it wants to cut off, almost. So Any advice would be greatly appreciated at this time, thanks.

I think you should post this under mazdaspeed section so people with MS3 can easily help you more. Maybe a mod can help you move this.

You gapped an Iridium plug?  I wasn't aware this could be safely done.  Anybody with experience on this? 

Perhaps improper gapping of iridium plugs caused damage to the electrode leading to this.

I contacted NGK and they said that I gapped the plug to much, Thanks o'reilys auto parts, lol. Well, I went to a turbo place in pensacola yesterday to have a compression test done. Well, everything looked normal, except for my number 4 cylinder was 10 less then the other 3 so... I alright toke the car to the dealership to see what they had to say. I only told them that I had a dp and an intake so, I'm hoping their shop needs work and will look past the mods. But the weird thing is, my check engine light will come on then go off, and I only hear the clicking noise when I get on it, but if I'm not in gear. then I can floor it and there's no noise, so I'm thinking, idk, lol. Even the shop yesterday couldn't really figure it out so......

I think if cylinder 4 is 10 low, it might be best to do a leakdown test. This might offer some insight as to what happened.

I haven't conducted the leak down test yet but I did take my car to mazda and now they could help me so. I'm thinkin either one the valve is damaged from the electro coming out or two the turbo is damage if the electro came out the exhaust. The car runs fine just at about 8-20psi of boost, it starts making that noise. and it comes and goes and I reuploaded the coob map onto it and then it doesn't do it as loud so, idk what to do next, besides what you'll said about the leak down test.

So my engine warranty is now gone so, im taking my car to fighters garage in pensacola monday for a leak down test to see if my valve is really leaking. Also, I'm going to get a bore scope tomorrow from my shop to look up from where my test pipe and down pipe meet to see if the turbo is damaged in any way.

You should have unmarried your accessport with your original ECU map..

You left the stage 2 map on there when you took it in?

I uninstalled the accessport before I brought the car up there. Some of the guys in my shop are telling me to convert the car compeletely back to stock and take it to another dealership and pray to god the dealership didn't report it. Which for my luck, they did, lol. Also, I'm gettin told by people that I might just have to buy a hole new motor, b/c that electro could of done a shit load of damage. Like scratching my cylinder walls and the oil smell is from an broke piston ring. So what would you guys do if you were in my position.

Then how we're they able to tell you had an ECU reflash?
[/quote]

There have been reports that the ecu can record/save the amount of times it has been flashed. So, if you have no record of having a reflash, then the dealership knows something is wrong. I do not know how true this is, but I have read it could be possible.

The way I read this is that he did not flash back to stock the first time, but after having his waranty voided, left, returned to stock, stock flashed his ecu, and went to another dealership. Therefore, the first one found the non stock map, but the second did not.

OP - It seems you've encountered some luck in this shitty situation. I hope more comes your way! Keep us posted.

no the ecu does not save the amount of times it's been reflashed it goes by version number and if the dealership tried to perform a reflash to a previous state when he took it to them to try to diagnose his issue which they probably did, then it either A.) wouldn't let them access the ecu which no piggy back does but since it was a reflash, the computer trying to do a factory reflash would have came up with an error because of the software being changed to a different "version"...

as far as the spark plugs are concerned... you NEVER NEVER NEVER NEVER regap an iridium or platinum spark plug they are set from the factory or they are the wrong plug if not set right...

I will disagree here... you MUST CHECK the gap on all plugs regardless of the metals they are built with. Of the two sets that I have purchased, only 1 plug was gapped appropriately. You can gently gap them with love taps... but the metal is pretty soft.
