I had intermediate issues with my car going into limp mode, I stop and restart it, I read a bunch post about how fix it. The only way to really fix is to replace it , it is the the whole throttle pedal assembly. I found it at o'Reilly, for around 400 bucks, but a lot cheaper than going to the dealer. I had a P0122 code , my problem was at start up I had no throttle , I would restart it and it would be fine, but it set a check engine light and a code. I changed it and it fixed it .
