Are your heads ported or stock? What about your intake? My car when its cold cranks for a long time and I have to pump the pedal a little to get it started and it idles a little rough for about 5 seconds and smooths out. My heads are gasket matched, not fully ported. A few people have said that if your cammed with stock heads, it may be a little harder to start.
On a side note for the future, its really not smart to take a stock motor, throw a cam in it and call it a day. For it to perform as best as possible and run good, you want the supporting mods for it. Tune, exhaust, ported intake and heads, 1.6 rockers, bigger fuel injectors, fuel pump, throttle body, better plugs, wires, and opti, etc. So many things need to be done for it to run tip top if it is cammed.

My heads are stock but I am going to get tune after the engine runs and ordering exhaust but the valve train has been upgraded for the cam and is new. And I was told that I can run with it on stock injectors. But if I give it gas then it runs at like 100 rpm then it will die if my foot is off the gas. Any more ideas?
