I put the OEM back on after jamming them full of heater hose to stiffen them back up (mainly to test the theory that the Anchors were trash). The anchors are in the metal bin at work.Aftermarket engine mounts are the WORST. They are Asian garbage. I had to change the engine mounts in my 03' Totota Solara. OEM were not available anylonger. Had no choice but to go aftermarket. Now I need new teeth. The vibration is INSANE. But, I'm stuck. When the car is in drive, and stopped at a light, it's the worst. Then if you turn on the A/C, you really start shakin. But, I'm getting used to it. ( have no choice). Go get OEM engine mounts and that will solve you're problem.
That did improve things to a point I was able to ignore what little vibration remained. The 1200 RPM stutter is new.
