Oldsmobile Bravada constant shaking and stalling issue on Oldsmobile Bravada

Some Oldsmobile Bravada owners report experiencing constant shaking at idle, which may smooth out upon acceleration, potentially indicating engine misfires. Additionally, some owners have noted stalling at stops, which could stem from misfiring cylinders, bad motor mounts, or engine damage, as well as issues with the fuel, air intake, or ignition systems. Specific scenarios, such as stalling when stopped at a red light with the transmission in "D" and the AC on, have also been reported, particularly when idle RPM drops to 600rpm or lower. Furthermore, a stuck EGR valve has been linked to rough idle and stalling, often triggering the check engine light. It is advisable for owners experiencing these issues to consult a professional mechanic for a thorough diagnosis and resolution.
