So I think I may know what my problem is but I want to get some input of what you guys(and girls) think.
I have an 03 that is stage 2 and a K&N filter and the silencer delete. Only about twice a month after my 20 mile drive to work I will be sitting in traffic waiting to get into my parking lot my car will idle high. This has also happend 1 time after I got home from work and left like 10 minutes later to go to the store. The high idle is around 1500-2000 rpms. Now if I try to drive when the car is doing this whenever I shift the rpms build about 300 rpms and hold a second before falling.
I am thinking that I need to clean my idle air control valve. I will do that this weekend when I get a chance to pick up the gasket. Is there anything else that may cause this problem?
