Hi,
Just recently my 89 mazda rx-7 wont idle.If i hold down the gas just a little bit,it runs just fine but as soon as i let off of the gas,it tries to idle and just dies.Ive changed the sparkplugs/did a tuneup and i tried to adjust the idle by screwing in that little idle control valve on top of the throttle body and it still doesnt idle.....Anyone have any suggestions on what could be wrong/what I need to do?
