I had the same problem with my suburban. I bought some massflow sensor cleaner and took off that part of my intake. When you look through it It will look like a screen on one side and little springs on the other. Hey that cleaner and spray the hell out of the springs and screen and put it back together. Also get some seafoam pour 1 in you tank and one in your intake while it's running and it will help a lot. When you put it in your tank wait till it is empty go to station full up with 16 gals pour it in there with that and take a ride. It cleaned mine out really well and she is running good.
