I have a 2001 Toyota corolla with 150k. If I rev the engine with the car in neutral and my foot off the clutch, it starts to shake at about 2-2.1k rpm. It will also start to shake at 2.5-2.9k rpm when the car is in gear (I can feel it in any gear but it’s most noticeable in 5th gear on the freeway).
I just replaced the spark plugs (I know, should have done that a while ago…) but it still has the same vibration. I’ll be doing a compression test later today, but I did take a few minutes to check out the motor while the hood was up. I set up a camera and recorded the car from start up and hit 2.1k rpm a few times. The vibration isn’t visible but the engine jumped a little right at start up.
Are the motor mounts bad? I’ve had that same vibration but a lot less intense since I’ve had the car, but it recently got a little worse.
I uploaded the video to youtube. Search “corollaprincess361”
