My 95 SR is all of a sudden doing a lot of stuttering. I thought it was because i put regular fuel in it, but its still acting this way even with premium fuel. It happens more at the lower RPMs (2 and under) or going uphills. It doesnt appear to happen all the time either, although yesterday it seemed pretty bad during a 45min drive.

Does anyone have any ideas what could be the issue?

Thanks

EDIT: No check engine light is on
