From what I gathered from Menards post, an out of range sensor wouldn't throw a MIL/CEL, therefore it wouldn't ve picked up on a code scanner. This would also lead me to believe a flashpaq wouldn't interfere with the system. I'd have the dealer scan the sensors

 

So the third code reader said tps1 and tps2 error. I found out that the the throttle body position sensor is internal... So this means a whole new tbps. What I don't get is that it only happens when the weather is around 60 or below... Ominous deployment now, it's 70 back in Florida and my wife hasn't had an issue for the past week... Does this make any sense to you guys?

 

It's normal for electronics to malfunction at cooler temperatures, but work fine at warmer temperatures. When this happens it's time to fix, or if it can't be fixed, replace it.

 

Temperature should have nothing to do with it, unless you are talking about extreme sub zero temperatures

 

I see dying maf sensors do that all the time on rovers. Unplug the maf and it goes into default mode and starts. Just another idea to check, the jk is probably different.

 

Ah, yes it does. Happened to me numerous times with different car electronics.

 

Buy better stuff....

 

Just going to do the viper tb mod... why not. people have posted on here saying 130$ for the viper tb... I'm not finding these prices anywhere! Fun part is going to be trying to talk my wife through the install...

 

Well. It's not the throttle body! And it's apparently ten times worse. My wife says if she turns the jeep off it won't start again unless it sits for at-least a half hour.... She's going to the stealership tomorrow so they can most likely throw parts at it...

 

It sounds like the fuel pump. I had a Ford Truck that would not crank at random intervals. Let it sit for a while and it would crank right up. No codes. Changed pump and filter never had any trouble again.
