erratic tachometer & engine vibration on 1st gear acceleration
Is it normal for have an erratic tachometer at the initial engine start? the dial jumps erratically up and down and then then stablizes after the initial warm up and RPM drops down to normal range (~600-700 rmp). Also, i felt either tire skipping or cluth skipping when i was trying to accelerate from stand still to high way speed. I initially thought it was cluth-gas coordination, but i felt the same thing when i was pulling into a parking lot at a much lower speed. (2005 325i, 45,000mile).
thanks in advance.
