Insane 1500+ Idle when engine is cold
When I start my car in the morning or after work, it idles at 1500+ RPM! I don't understand why. If I start it warm, it idles at 550-600. I don't know if it's related to my cold engine starting problem (takes forever to start, like you had a low battery - even though the gauge reads 12+V)

mine idles at about 1200 when I first start it but when I turn the air on it drops to about 600.... I dont make much of it. You might want to get an idle pully witch will help the engine idle normaly....

the initial high idle is just the warm up loop. after a min the idle shoudl go down to normal.
as far as the hard start it may just be the car waiting for full fuel pressure to reach the injectors. our cars are supposed the be able to hold pressure in the fuel lines but over time the check valve in teh fuel pump will get a little beat. try turning the key to the run/accessary position and counting to 10 before you try to start it. tha twill give the fuel enough time to fill the lines.

NJ,
When I start it it will idle for over 5 min at high rpm. I let it sit there while I got ready for work last week to test. It didn't go down until I dropped it into gear and drove around. If I pop it into gear and back out it goes back to 1500+
Also, I tried leaving it in acc for a while before starting. I even tried making sure the radio, ac and everything were all off.
The weird part is, all that hard starting will drain teh batt down to just below 10V but never kills it. At least not thus far.

Is the Service Engine Soon(SES) light on?
Sounds like either a bad 02 sensor or throttle position sensor(TPS). They should shoot codes and your SES light should be on.

I have an open air assembly with a 3.16x14" K&N in it
I have not found any leaks in the intake
