My 98 Saturn has started vibrating really bad and when I push on the brake it really shakes the car and idles down to where it almost stalls out. If I keep my foot on the brake and use my other foot to push on the gas a little it stops vibrating. I took it to Autozone and it showed a misfire on Cylinder 3 as well as the code: P1641 (which we have no idea what that means). Also, certain times when I'm driving it, along the dash it sounds like water/fluid running. Bought spark plugs but was wondering if this will be an easy fix or is this going to cost us a lot to fix?
