when the car is cold (sitting over night) it will fire up as soon as i bump it... when its warm its more hesitant. sometimes i have to press the gas. also when its warm after driving itll have a high idle (1500-1700rpm) when put in park.....i cleaned the IAC and no luck... anybody with this problem? thanks

 

Check your fuel pressure. Also, does it have a long start at all or is it just a high idle?

 

fuel pressure 42lbs... high idle after driving and its only 75% of the time... doesnt do it everytime?

 

Test your fuel pressure regulator.
