Mazda 626 vibration and rpm idle speed
I think the vibration may be due to low idle speed.
I've noticed that the idle rpm drops slightly when I put the car into D or R from P or N.
When the car is cold, the idle rpm is 1500 and drops to 1350-1400 when in D or R. (with brakes applied) There is no noticeable vibration.
When the car is fully warmed up, I can't estimate what the rpm is because the tach gauge scale is so coarse. I know it drops by about 100-150 rpm for D/R. Then the vibrations happen. If I step on the gas a little bit and the brakes are still applied, the vibrations go away.
