Weird one today... I was driving around town and everything was working great but on my way back from the last stop I noticed the SHO was noticeably down on power.. I look over at my SCT device to check the vitals and saw the the knock sensor PID was stuck at 0 and wasn't adding any spark..
Rolled through and checked my OAR which is always pegged at -.96 and noticed it was stuck at 0 as well... checked my spark and realized I was missing a ton of it.. and the knock sensors weren't working..
Get home, turn the car off, and then turn it back on a bit later to go to the store again... (You never make just ONE trip to homedepot...).. Knock sensors are working again but my OAR got reset..
Really weird... I have no clue what happened... not liking the random non-reporting of the knock sensors.. at all...
Battery sufficient! Z
check the knock sensor wiring? pest issues?

Did it again today.... need to get the battery checked... gonna flash down to the LMS tune for now until I get this straightened out...
I have noticed lately it is idling a little rough and when the fans kick on it idles even rougher...
Sounds like a battery, fans draw a lot and sounds like battery is struggling with any kind of load. Good luck man
Mine never had an issue with the OAR resetting but I did get an intermittently rough idle when my battery was on its way out.
I need to grab a datalog as my knock sensors are pulling almost 5 degrees in 3rd gear. Also noticed my car was seriously down on power and that would be my culprit. Suspected had gas. OAR is still @ -0.96 though so IDK....

I think Brad used to have his tunes set to pull 2 degrees of spark for every +1 of KR... so if you are pulling 5 degrees of, then you are probably on seeing around +2.5 KR which wouldn't be enough to move OAR.. anything over +4 or higher should start to raise OAR..
If its something new, then its probably bad gas, if you have some E85 nearby you could throw a gallon or so into it so see if it stabilizes it.
Yea, my idle has been rough lately...
Thanks for the info Stealblue. I'm not trying to thread jack but I do appreciate the insight.
I saw +4.5KR briefly. I thought that was 4.5 degrees total.

Depends on how he has your tune setup.. that could be as much as 9 degrees pulled... Brad is aggressive on pulling spark when the knock sensors pickup possible knock conditions... which is good thing as far as I am concerned.
When your battery was bad, did you take it to local shop to have them test it? or had it gotten bad enough to know that was it?
Looks ominous..

I took it to my mechanic and he tested it. It was the OEM battery so not to shabby. Replaced it with the BTX65850 recommended by many on the forum.

New Battery is in order.! It kind of explains the intermittent issues. Z

Getting battery tested today... the KAM is getting reset in middle of driving for some reason... plus the rough idle and rougher idle during fan operations seems to indicate either a battery issue or connection issue.. I hope its not the alternator.. getting that checked too..
So battery tested at 558 cca... after a 20 mile drive. Battery has been replaced. Alternator tested perfect.
Hopefully that was the issue... we will see...
Fingers crossed!
Definitely idles much better now... time will tell if the KAM doesn't reset while driving... it's a 21 mile drive door to door from my buddies shop... almost home... so far so good...
X2 - Fingers crossed bud. Z
Curious... is the stick battery only 650CCA? That is what was in mine... I went ahead and put in the 850CCA.. I figured with the alky pump in there it wouldn't hurt to get a stronger battery.
yes stock is 650 cca.
Been hammering on it today trying to replicate the OAR/Knock issue. Seems to be gone... amazes me how sensitive these components are to voltage deltas.. Honestly, if I was monitoring my car like I do with my SCT programmer, probably wouldn't have noticed it much till I went to the track...loosing 12+ degrees of spark is however pretty noticeable...

Do you have a log or just watching handheld?

It was happening randomly, so I never was able to get a log... but the hand held has min/max and nothing looked out of line? It wasn't like there was a massive KR event and the car went into limp mode per se... I WAS initially worried that something let loose and the ECU could't read the timing correctly so it disabled the knock sensors and reset OAR! HOWEVER, I noticed my LTFT's were also reset back to 1 for all loads.. so it made more sense that something was resetting the KAM.. just didn't suspect the battery until I posted on here...
Another interesting thing was that in lugging situations (I live at the base of the mountains so its EXTREMELY hilly where I live) at 50+ mph (or 6th gear) it felt like the car was struggling a bit.. however, with the new battery that seems to have abated as well... dunno.. could be placebo but the car is running A LOT better..
Great news!!!!
Freaking weird... happened again.. car is running better.. not sure why my OAR keeps resetting... battery obviously needed to be replaced...
at this point I believe I am chasing an electric issue..
Just threw a code... P0020... Camshaft Position (A) Actuator Circuit (Bank 2)..
Wonderful!
Check fuse # 67 on (BCB). Z
Check for any frayed wiring that run under the radiator and underneath the battery box .

Battery compartment fuse box.
The chaffing would make sense... I was doing some testing and noticed that the OAR reset and the P0020 code happened at the same time... when I moved the gear selector from D to R... the gear change made the car jump a little (I am on a hill) and that's when everything happened...
I don't have a fuse 67 in the fuse box next to the battery...
I am also getting acid build up on the positive terminal on my new battery... this is screaming like I have short happening somewhere...
Sometimes a pin in the wiring loom gets knocked loose. FoMoCo was the first to mention this happening, albeit on a Gen 5.
On the front cam cover, check the vct plug and follow the wire back. Mine had no slack and was chafing on the block.
The wiring in these cars is disgraceful....
Damn good luck you will get it!!!
Reset the connector, checked things over... and called her all kinds of nasty names... so far so good....
