Just to cover the bases. I have an 06 cobalt ss/sc with about 42000 miles on it and it is stock under the hood. I got in my car today and started driving and noticed the boost gauge was moving in little increments and it didn't feel like it was boosting all the way like normal. Any help on what might be wrong would be appreciated.

 

yea i posted this question like 2 weeks ago mine is doing the same thing, its almost like the needle is sticking, everybody has told me that my gauge is broke, so i think thats what it is, as far as my problem...
