With Polar Vortex 2.0 gripping Wisconsin, I'm once again having problems with my Grand Cherokee !!!error: Indecipherable SUB-paragraph formatting!!! . Likely fix is to clean the idle air control valve but I haven't gotten around to doing it.

!!! UNKNOWN CONTENT TYPE !!!

Another problem I've been having only when it's too damn cold out is it kinda struggles to reverse. I thought this was just from the driveline being cold but today I got a check engine light.

Auto Zone pulled a code P1784, which is one of the pressure switches in the transmission not working right. There are 2 likely end results to this: clear the code and it goes away, or the transmission needs a new solenoid pack.

For whatever reason the guy at Auto Zone wouldn't use his scanner to clear the code. So I'm going to get one of these bluetooth OBD2 dongles and use my phone to clear the code. If it doesn't come back, then I'm fine. If the CEL does come back on, then I won't have to bother with going to get the code pulled, and I can just take it right to a shop to worry about the solenoid pack.

Plus...it's a new gadget to feed my addiction.

I've had the same problem with autozone. I solved this problem easily, I stopped going to autozone for anything. Advance and O'reilly will let you clear it and hence that is where I buy my parts from now - more Advance than O'reilly.

I've used a scangauge for a long time as my OBD II reader/code clearer for a long time but it's going away with the Miata I just sold. I just picked up one of the 20$ Chinese bluetooth senders on Amazon and it works perfectly so far. I don't know why anyone who has a smartphone and a post 1996 vehicle wouldn't pick one up if they don't have a way to read codes.

I usually go to O'Reilly. As I was driving to work this morning, by the time I decided to go get the code pulled, I had already passed both O'Reillys along the way to my office. So...I ended up at Auto Zone.

I suppose I could go to O'Reilly on my way home, but at this point I already got the dongle for $15 shipped overnight (thanks Amazon Prime). I've actually wanted an OBD scanner for a while anyway so for $20 total cost when you include the Torque Pro app, that's totally fine by me.

I keep on in the car with me at all times, awesome tool for monitoring your diagnostics.

Don't get me wrong, I have one as well, but I use torque free

I'm going to try the free version first. But there was a note about the free version maybe not working with certain Chrysler/Jeep vehicles so I assumed I might have to get the paid version.

My adapter may be toast since I drove around with it in for a day, trying to catch a code. After that day I can no longer get it to connect in any car. The only thing I can think of is that it got too warm and un-soldered something inside. For $20 I will prob cut it open and see if I can fix it.

Is there a good app on the iPhone? I know torque is awesome, but only available on Android. Other than diagnostics I'd like one for monitoring the mpg to find the sweet spot for speed.

I know they exist but I've never used them.

You could pick up an outdated android phone and use it. I have a four year old phone loaded up with mp3s that I mount when I want gauges.

Good idea. I could also sack up and get the new nexus, but we will see. Thanks for the tip.
