i changed spark plugs 2 weeks ago. I noticed upon start it takes sometimes 2to3 turns, sometimes starts right away. The rpms sometimes jump to 2500, and im idle at 900 which im told its pretty high, anyway i was told maybe fuel injectors clogged, i tried slick 50 and no luck, any ideas to what might be wrong, and i would make a donation but not sure about this website, and i would rather donate after i get a mental picture of what mite be wrong, im sure the donation would be nice if i know whats wrong,lol

First, 2500 RPM's is very high for an idle. Has the check engine light come on? Second, I would start with checking fuel pump pressure regarding the hard start. Chances are the pressure is dropping off when you shut the car. Then, it takes the pump a few seconds to rebuild pressure.

Let me know about the check engine light.
