Car Wont Start without JB3??
So I started getting a really rough idle, for the last few weeks, only in the morning when I start the car. Well this morning, I could not get it to go away, and got a service engine soon light, and when I did a "check control" the spark plug symbol lit up. Well I figured I have warranty i'll pull the JB3 and bring it in... well when I pulled the JB3, and made sure all the connectors were in correctly it wouldnt start. It would crank for about 20 seconds, and then just stop with an ! on the dash info. So after checking the connectors a few times, and getting the same result, I figured I'd put the JB3 back on and see what happens.. BAM starts right up (with service engine soon light on). Now I have a set of Spark Plugs, and Spark Plug tool (I got it from a member a while ago) but have no Idea on how to change the plugs or if that will even fix the problem. I do have a BT tool, but my computer died (writing this from my phone) so I'm waiting for it to charge up to get some codes. Anyone ever experience anything like this? What would you do? I'm really confused why the car wouldnt start without the JB3 installed.....
BTW the car is an 07 - w/ 40k miles. I dont believe the plugs have ever been changed.
