Misfire count and should i be worried??

[TyphoonFiST]

Do you have stock spark plugs? My car was showing a decent amount of misfires as well but I know what a stage 2 tune on stock spark plugs isn’t good. I have my #6510’s coming is asap.
I also run a gallon of e85 and run a ots 93 map and that helped a bit with the misfires

Mileage?

Keep us up to date with your findings after you put in new plug's!

It may not be meeting the threshold of setting off the check engine light.....If you have a scan tool you can use Mode6 to look at each individual cylinder and go from there. Inspect spark plugs very carefully also. As the monkees that do shipping and handle them in parts stores drop or throw them around during shipping/ stocking the shelves. Food for thought I guess....let us know how the plugs turn out. Also I see your OAR is getting below -1.00 this can indicate Poor quality fuel also.

thanks for pointing the oar dip I got so use to seeing -1.00 that I didn't even notice that dip until you pointed it out lol that definitely could be an issue.

What's the verdict?

Okay so I got the #6510’s put in today and I don’t feel that much a difference. I think it helped tho.

People really need to stop looking at their accessports to find reasons to think things aren't going well with their car. If you are genuenly concerned, take a data log of a wot pull and either send it to your tuner or learn up on tuning parameters. This is getting old.

on another note I put gas from a different gas station closer to town so far not seeing any more - corrections so thanks for the info it was most likely a shitty gas station I went to recently also oar came back up to -1. thanks to the rest of u for the input.

Any perceptible difference in power, torque, responsiveness?

Update: I'm only seeing misfires when i'm in a higher gear at lower speeds and i accelerate at a lower rpm than normal.
Also switched back to 91.
Will be getting a tune from Dizzy so i'll see what he has to say about it.

There is a certain amount of misfires that are deemed acceptable in most vehicles it just depends on where the manufacturer has set the threshold of where the check engine or service engine soon light illuminates. Cars misfire and sometimes it's just not enough to set off the light. FYI This is where Mode 6 comes in with a scan tool to observe misfiring cylinder that wont set off the check engine light.

Mmm I see.
Yeah I don't see any negative corrections and my OAR doesn't ever go below -1.00 so it must not be major enough to throw a code.
Thanks!

Well maybe because that's the number one thing you don't do in di turbo cars. Lspi heaven and thr quickest way to spin bearings. Never punch it in a high gear at low rpms ur just lugging the engine.

As long as the oil pressure is good, and aren't getting that tell-tale 'chatter' sound, (associated with "lugging",) shouldn't have to worry about damaging the crank bearings.
