    Hey everyone,

    Recently picked up a 2013 SHO with 76k miles on it. I was driving on the highway and gave it a little gas and the check engine light came up and I started losing power. I pulled off to the side of the highway, shut the car off, turned it on, and the light went away and was back to driving normal.

    I've researched this and a lot of places are saying it can be either the spark plugs, coil, or the fuel injector. Has anyone experienced this?

    You should check with a scan tool if any codes are set. Otherwise just guessing. Might point you to a specific cylinder, then you can try swapping parts or checking plugs.

    I’m in the same boat. It drove perfectly fine after I turned it off and on. I was able to accelerate with no issues. I’m taking it to the dealer I got it from tomorrow and they said they’ll check the code. I’ll give an update once I know.

    Get codes checked , or pick up a inexpensive code reader. Your cars loss of power was probably your car putting itself into Limp mode to prevent any damage. Cylinder misfires(plugs/coil/ injector) will trigger limp mode even a lean condition shown from O2 sensor. By turning car off and restarting it starts new run cycle and if no problem detected no limp mode but code for previous fault is stored.

    It is funny you say that because I agree. I scanned mine with TQ while going to down the freeway. Engine light flashed for about 40 seconds. The scan said misfire cylinder 1. Before the scan was complete the engine light stopped flashing, and the car went back to normal. Hasn't had a hiccup since and that was 400 miles ago. So I am chalking it up to something going goofy for a second. When I get it back from its recall work, I will check cylinder one plug and swap coil 1 and 4.

    I just drove to work (about 55 miles) and didn't experience an issue. I even opened it up quite a bit on the way and all went well. I'm still going to get it checked out.
