So this is new... It will start on the 2nd or 3rd key turn. It cranks but won't turn over immediatly. Doesn't happen all the time either. I noticed it running at a high rpm until it warms up. I'm confused. Distributor cap is fine and I just changed plugs, wires and air filter.
Any ideas are appreciated.
Thanks:)

What engine?
Any codes or check engine light?
Fuel filter or fuel pressure been checked?
