Shoboat the fact that it goes away when u return to stock tells me all I need to know and it's all tune....and that the torco helped...that is the stuff I would've said to u use I just didn't know if u had that up there in canadia lol.

And as far as u being surprised that more people don't notice Id say because people don't pay as much attention as u...I've honestly never looked at my spark and knock sensor at part throttle...1 because I didn't adjust timing in that area and 2 engines can tolerate much more timing advance and some knock because it's under light load....and I also wouldn't worry because u are not actually knocking it's pulling timing to prevent it from knocking

All very true, As you have already noticed that I am a little OCD when it comes to my rides ;) I'm not terribly worried about it, I just need to know why. I understand that the tune is responsible for the issue. I am however convinced that the crappy "winter gas" seems to have a bigger impact on the why now. I am waiting on a friend of mine to get his depot up and running for the season. Once he does I will try a fresh brew of his 100 octane no Ethanol go go juice. I ran that at the track last year with great success. I know what you are going to say. Duh it's 100 it can't pull timing with that in the tank. Well if something has changed in my car it just might. Also the stations around here will be getting their summer gas by the end of the month. I will also be interested to see what that does if anything. I plan on doing an extended log with Forscan with Knock counter and Misfire counter set up for the individual cylinders. I'll report back.

SHOdded. I did take a look at that. I am not positive but judging on the timing (no pun intended) of the KR events it seems unlikely.

For reference. I monitor KR religiously, have it on a gauge that keeps the max and minimum. The winter fuel arrival spiked my KR pretty bad. Figure the tune is way more sensitive to bad fuel than the stock calibration, I mean it can run 87 stock. So putting the tune in which demands a higher octane most definitely shows that the safeguards remain with your tune.

This winter fuel issue sparked my thread about it back on its arrival this winter.

Have you checked your messages for the work in progress formula to LOR gauge. This could determine if it is indeed the fuel or something else.

So another update, KR is all but gone. However my misfire is back with a passion. Only over 4500rpm, and only in 2nd and 3rd. I did some logging last night. I have replaced the plugs and boots. Checked all the hoses for potential leaks. Nada. I tried the 93V8, 91V8 3bar tunes and the 91V8 2bar. Pulls smooth with no misfire on the stock tune.

Back to possible fuel injector issue then?  Probably did not set a code either, and if so, would need service shop/dealership to diagnose.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Are you getting the genetic misfire code of p0300?

No misfire code, however I did look deeper into the logs from last night. And it looked like it was cylinder #6 that is the culprit. I decided to swap the coil packs from 4 to 6 and took it out again. It did misfire again once in 2nd gear. (the first pull) Then it was gone, I mean totally gone. Try as hard a I could to get it to and nada??? From a dig to quite fast ;) several times. And several 2nd to 4th gear pulls. Got home and looked at the logs and cylinder #6 had one demand misfire on the first pull (2 actually). Then completely normal. So I am guessing 2 possible causes at this point. The injector was dirty and suddenly dislodged what ever was in it. Or a bad wire or connection to the coil pack on #6. Any further insight would be great.

BTW thanks for all the ideas. Bouncing stuff off you guys has been very helpful.

Loose connection is looking more probable, as long as the misfire does not return.  Sometimes it takes a while to show up after.

A few screen shots of the logs. First is the misfire event and 2nd is no misfire.

So I decided to look closer at the wiring on the #6 connecting to the coil pack. I checked the wiring and cleaned the connector with some contact cleaner. Nothing obvious here. I did decide to for a joke swap the #6 plug with the #4. Keep in mind that this is the second set of plugs I put on the car this spring. The NGK's could have been fouled as they had 10K of hard km on them. I then bought a set of SP534 from Ford. And guess what Not a single event on #6 during the drive. There were a few non demand misfires on the #4 though. So it may very well have been a freaking plug. Not discounting the fact that I also cleaned the connector on #6. I will keep an eye on it over the next few days and just to make sure that it was the plug. If it was I should eventually misfire again. Only time will tell.

Well, you've made sure quite a bit of stuff is working right, on the bright side of things.
