When i am in 3rd, 4th, and 5th gear going about 2000-2500 rpms and try to push the gas to speed up 10 or so mph my car seems to lag or something. Like it isn't getting enough gas or something is slipping. Once i get to about 5000 rpms it is fine but going from 2000 to 5000 it defidently doesn't feel right. Anyone know what might be wrong? Loose belt, fix timing?
thanks
