I'm not trying to give you crap but why ask here? You shouldn't be seeing voltage in the 11's with a new battery.
I mean, you just bought a battery from a dealer 3 months ago and it already conked out. You should be at the dealership right now having them take care of it. Honda batteries...
I was able to track down that old edited post from the guy I mentioned the other day. Sadly, it's another hatchback rod failure (#14). It's mind numbing that 14 of the 17 (82%) Non-Si rod fails are FK7's. I also added his car to the failures thread...
Stock, our models have a very low idle speed (it's to save gas). When the car reaches normal operating temps you may see idle below 700 at times. I experienced this. My front passenger seat would literally shake at traffic light stops. There's nothing wrong with your car, that's how Honda...
@cheezer4998, a couple things.
First of all you added your car to my tuning thread two years ago when you first tuned. Could you please add a new post there with your current info (tuned miles driven etc.). It's really a big deal...

Glad the PCM was covered under warranty.
That's why I sheepishly said "how's the coolant level?". When I put the misfires and stuttering together with cold start wonkiness it started to make sense. Plus most of the 10th gen head gasket issues have been Si's driven hard on higher powered tunes.
I think the consensus is to get another...
That's fine man. You have to understand this is an enthusiast forum and you're original post talked about "needing torque" so we responded accordingly. I get it now. Thanks for the explanation.
