Hello internets.  Been a while since I posted, but wanted to share a repair I just made to my car.  I’ve been researching for months why my G stalls out when babying the gas in stop-and-go traffic, or reverse, or pulling into the driveway.  I have about 88,000 miles and it drives great when the rpms are above 1000.  When they hit 1000, the engine seems like it’s choking and many times will stall out.  This has been happening for a very long while now and I’ve searched and searched for a definitive answer to no avail, until last week I stumbled upon something.  The forums for infinity owners are outstanding and based on lots of reading, there are several things that could cause stalling.

  1. Mass Airflow Sensors – either bad or dirty.  I cleaned mine with MAF cleaner spray multiple times which didn’t help.
  2. Camshaft sensors
  3. Crankshaft sensors
  4. After market air filters – which ultimately lead to #1
  5. Dirty throttle body

Normally if there’s a problem you will get a service engine light, which you can take to any local auto parts story and have them provide a printout of the reading.  Typical codes mentioned related to this problem are P0024, P0014, P0133 (maybe).  I was not receiving any SES, which made this that much more baffling.

To make a long story short, it turns out that PCV valves can choke an engine when they go bad.  See the article below for an explanation of what they do/how they work.

I bought a $6 replacement value from Amazon…this one specifically: https://www.amazon.com/gp/product/B001UEBXD8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Once the old one was out and the new one in, there was no more stalling/hesitation/choking.  Like magic!

What a PCV does:  http://www.agcoauto.com/content/news/p2_articleid/197

To replace the PCV you need to take off the passenger side intake body.  The valve is located directly underneath (labelled on the engine).

Good luck!

*Update 12/23/16 – after a couple weeks of running fine, it started hesitating and stalling again.  Decided to take it to local Nissan dealer who diagnosed an out-of-date software version in the ECU.  They updated the software and replaced the spark plugs.  It hasn’t died since (about 3 weeks ago), but it has again started to hesitate coming off the line.  The dealer also recommended a full fuel system cleaning ($100+) which I passed on.  If things get any worse, that will be my next course of action.  *sigh*

If you need to capture SSL trace information when making an HTTPS call from your web application running under Websphere 7, add a jvm -D property for javax.net.debug with a value of ssl and any other additional tracing levels as defined in the link below. For example:

-Djavax.net.debug=ssl,handshake,data,trustmanager

Refer to this link:
JSSE Reference Guide

This will allow you to see trust store information, certificate chaining details and other information that should help you debug issues with making https calls from your server. If you are trying to connect to a web server that has a self-signed certificate, you’ll need the signer cert added to the \java\jre\lib\security\cacerts keystore within the Websphere install directory. Note – the default password for keystores is “changeit”.

Here’s an example of the output from the tracing. You can see the trace tells you the location of the cacerts file used for cert lookup:

The 2009 Cary Jr Trojans season is over.  Last week was superbowl weekend.  4 out of 5 Cary bantam teams made the playoffs, and 3 out of those 4 made the superbowl.  Truly a fantastic group of 7 & 8 year olds who should continue to be successful as they move through the levels and into high school.  Some say the current Cary Grove high school team had the same success when they were bantams.  Let’s hope as a group our bantams can be just as successful.

Oh, guess which of the 3 teams lost?  Yeah, mine.  It was a heartbreaking loss.  We beat ourselves.  Mistakes, penalties, and a fumble on the 3 yard line.  We lost 0-7 to Woodstock.  I wouldn’t feel so bad if they dominated us, but we really should have won that game.  Our defense held their own again, with the only big play for Woodstock coming with our middle linebacker on the sidelines recovering from a hit.  11-1 is a fantastic season, but the loss is a bitter pill to swallow.  Only 7 months to wait for next season.

I have a project at work where we’re looking to present a user with an edit message if they’ve changed anything within a web page and haven’t saved the form before closing the page to stop them from losing changes.  The following example works with IE 6 (which is our corporate browser).  It does not seem to work with firefox, and I haven’t checked with any other browser since our need is isolated to IE.

<html>
<body>
<script type=”text/javascript”>
document.write(“Hello World!”);
var needToConfirm = false;
//Call this function if some changes is made to the web page and requires an alert
//you could call this is Keypress event of a text box or so…
function setDirtyFlag()
{
needToConfirm = true;
}

//this could be called when save button is clicked
function releaseDirtyFlag()
{
needToConfirm = false; //Call this function if dosent requires an alert.
}
window.onbeforeunload = confirmExit;
function confirmExit()
{
if (needToConfirm)
return “You have attempted to leave this page. If you have made any changes to the fields without clicking the Save button, your changes will be lost. Are you sure you want to exit this page?”;
}
</script>
</body>

The game was back and forth for a while. Then in the top of the last inning, the Braves scored 8 runs to go ahead 23-16. The A’s determined not to give up answered with 8 runs of their own to win the game.  It was a great come from behind victory to end an exciting game.

We’ve heard blood curling screams following a big loud crash enough from the boys that we don’t tend to overreact anymore, but something in the scream this morning sounded a little more convincing. All three boys have been wearing their brand new Crocs around the house which they tend to do when they get new clothes or shoes. Tooling around in nothing but underwear and Crocs is a sight to behold.

So we’re eating breakfast, and Jake gets up to go to the bathroom. He takes off down the hall like he just broke through a gaping hole off-tackle and somewhere in between juking the wall and stiff-arming the door, his Croc stuck to the floor and he got tripped up and and landed chin first on top of the toilet. Loud crash followed immediately by horrific scream.

I wish I took the picture anyway, but he wasn’t interested in documenting the gash for posterity. It was the shape of a football and as deep a wound as I’ve ever seen. I’m pretty sure I could see his chin bone through the blood. After sending Braden and Logan to the neighbor’s to play, we took a trip to the emergency room. An hour and a half and 9 stitches later, we’re back to getting ready for our baseball game.

This isn’t the first time we’ve had issues where running with Crocs on has produced a boy-on-floor scenario, but is the first time where a toilet got in the way. I guess toilets are a lot like middle linebackers – you’re better off avoiding them than trying to take them head on.

<Update Friday 4/4>: I’ve uploaded the practice/game schedule.  Click here to view.

What a hectic day. With Tasha gone on business until Wednesday night, it was another day to play Mr. Mom. These days just fly when there’s stuff to do. We had our first baseball practice tonight at 4:30. That was just early enough to rush us through after-school snacks and get half of our homework done and make it a sprint after practice to finish homework, eat, read, nebulize, and play DS before bedtime. Practice was good though. The boys had fun. Their coach seems nice. He stressed having fun and seemed to be very good with the kids. We’re looking forward to a good season.
The 2008 Baird baseball roster:

Logan – #6
Braden – #1
Jake – #5
