Ok I am now the poud owner of a 95 Z34. When I start the car up in the morning, or when she sat for a while she revs up and down and even stalls!Anyone have an idea of why she does that? I cant figure out why! Thanks

 

is it reving on its own or do you mean whne you rev it? i've heard of this problem on the forum, but i can't remember what it was. get it to Auto Zone and they can scan it for free. I think its the throttle body. How many miles are on your car and is it stock?

 

The car does it on its own, as for the miles its around 145,000, and stock. Can Auto Zone check it without the Check Engine Light on?
