I installed the sprint booster for my 2011 Wrangler sport. Felxible version. But I get the ETC light flashing after I install it. Then I can take it out the ETC lights disappears. I tried it twice. Anybody have this issue?

 

I installed one in my 2011 Rubicon about 1 month ago. Loved it until today when ETC light came on and left me with no throttle sitting in the middle of traffic. I shut off and restarted engine and was able to get moving again. ETC light went off, but check engine light came on and stayed that way. I got home, disconnected the battery, removed the Sprintbooster, reconnected the battery and restarted the engine - check engine light is now off. Am going to try and send the Sprintbooster back as I am now concerned about it happening again. I was in a reasonably safe place when it happened this time, but I would certainly NOT be thrilled if this were to act up in the middle of an intersection!
