I just finished changing my spark plugs for my 60k service. When I started the car, I had a rough idle and VSC light came on. After checking everything, I discovered that I had failed to plug one of the spark plugs back up. After I did that, I now have a nice smooth idle and the cars seems very responsive ( more so than before) but the VSC light is still on. Any suggestions? I've double checked to see that everything is plugged back up as it should be but I can't see any obvious problem.

 

Did you clear it? Might just be left over from the issue before. Sometimes it can take a while to clear itself. You could get an OBDII sensor and clear it yourself, or stop by Autozone and have them do it, then if it returns you know it's still a problem.

Did you confirm the MAF sensor was plugged back in tightly? When I last removed the air box and intake I forgot to plug back in the MAF and it threw a code.

 

probably just need to clear the code. If drive-ability is back to normal then it should be good.

 

Thanks guys! After making sure everything was buttoned up and a few miles of driving, the next time I started up it was cleared.
I was a little hesitant at first to change the plugs @ 60k, but I can sure tell a difference.
