Same thing when driving, if I do not let the car warm up for 15 to 20 minutes, I feel alot of vibration in the cab when I drive, until the Idle drops to 700 RPM and then it drives perfectly fine. I had the motor mounts checked, I was told they are worn - but seem to be ok.
My main concern is Engine Vibration - it is strong enough to make the hood and front fenders vibrate to the noise of the engine when warming up, then its fine!
Sensor check showed all sensors working!
I changed wires, spark plugs, and rotor cap/button.
I'm at my whits end to trying to resolve this - having several day - here and there - trying to figure it out!
Trying to avoid going to a costly repair shop - any solid advice would certainly be most helpful!
have the same problem?
