[QUOTE="Gruca, post: 16090292, member: 153163"] I just wanted to share my experience, in the off chance it helps someone else out. I’ve been driving my 14 Mustang GT off and on this winter and after 15 minutes or so of driving, the wrench light would come on and the car goes into limp mode. It throws no codes and if you turn the car off and back on, the wrench light goes away. Car drives fine otherwise. I thought it was the throttle body. It wasn’t. Wasn’t the MAF either. Long story short, it was the JMS boost a pump connection that connects to the gas pedal sensor. I always have the heater set to the floor and after it gets hit by the heat for a bit, it puts the car in limp mode. Moving it out of the way or setting the heat to a different place makes the light stop coming on. This is on a 14 GT with GT350 fuel pumps and the dual JMS powermax version 2 BAP. I only saw one post that vaguely mentioned it, which is how I figured it out on my car. So hopefully this makes it easier for anyone else that may encounter it. [/QUOTE]
