While driving up hill I feel a stuttering, thumping, choking kind of sound. This happens only when I excellerate quickly up hill. This does't happen from a stand still, it happens when I let go of the gas to slow down, then press the gas to excellerate. The speed or the RPMs dont change while I feel it. If I press the gas slowly, it's smooth. Could it be the regular gas I've been using? Dirty injectors? Anyone had this experience?
